Painful Sex (Dyspareunia)

What causes painful sex?

Painful sex — or dyspareunia — can have many causes, including pelvic floor muscle tightness (vaginismus), hormonal changes and vaginal dryness, infections (yeast, UTIs, bacterial vaginosis), skin conditions, endometriosis, structural issues, and emotional or psychological factors like stress, anxiety, or past trauma. Because the right treatment depends on the cause, a medical evaluation is usually the best first step.

Does painful sex always mean vaginismus?

No. Vaginismus — involuntary pelvic floor muscle tightening — is one possible cause, but painful sex can also be related to dryness, infection, vulvar pain, hormonal changes, skin conditions, endometriosis, pelvic floor dysfunction, or other issues. Many women have more than one cause contributing at the same time.

Should I keep trying penetration if it hurts?

Generally, no. Pushing through pain can increase muscle guarding, fear, and anticipation of pain — often making the cycle worse. A slower, more supportive approach guided by a provider or pelvic floor therapist is usually more effective. This is especially true if pelvic muscle tightness is part of what’s driving the pain.

Sex hurts and I can’t tolerate penetration. What are my options?

Your options depend on the cause, but they may include pelvic floor therapy, vaginal dilators, lubrication, treatment for an underlying condition, and support from a clinician experienced in sexual pain. For many people, the best plan involves more than one approach.

Vaginismus

What is vaginismus?

Vaginismus is a genito-pelvic pain/penetration disorder caused by involuntary tightening of the pelvic floor muscles that makes vaginal penetration painful, difficult, or impossible. It can affect intercourse, tampon use, gynecological exams, and any form of vaginal insertion. It is not a psychological condition.

What does vaginismus feel like?

Symptoms vary widely. Many women describe hitting a “wall” when attempting insertion, while others experience burning, stinging, tightening, or sharp pain. Some women cannot tolerate any penetration at all; others experience only situational pain. The condition can also cause significant fear, distress, and avoidance of intimacy.

How does vaginismus affect relationships?

Vaginismus can affect intimacy, communication, and emotional closeness in relationships. It can cause shame, avoidance, and isolation for the woman experiencing it, and confusion or feelings of rejection for a partner. Research consistently shows that how a partner responds makes a meaningful difference in outcomes.

Menopause & Perimenopause

Why does sex hurt after menopause?

Estrogen decline during menopause reduces vaginal lubrication, elasticity, and blood flow — making friction and penetration more uncomfortable. Pain can also involve pelvic floor muscle tension: once penetration starts to hurt, the body may begin anticipating it, causing muscles to tighten automatically and making the problem worse over time.

What is Genitourinary Syndrome of Menopause (GSM)?

GSM is a collection of vaginal and urinary symptoms caused by declining estrogen during and after menopause. Symptoms can include vaginal dryness, thinning tissue, discomfort during sex, and urinary changes. According to a national study, 57.4% of women experience vaginal dryness after menopause and 41.5% experience painful sex related to changes in vaginal tissue.

Can menopause cause vaginismus?

Yes — menopause can contribute to the development of vaginismus. When penetration becomes painful due to dryness and tissue changes, the body may begin anticipating pain, causing the pelvic floor muscles to tighten involuntarily. Over time, that cycle of tension and avoidance can develop into vaginismus, which is recognized as a condition on its own.

Postpartum Recovery

Is it normal to have painful sex after childbirth?

Some tenderness, dryness, or discomfort can be common in the first weeks after childbirth while tissues are healing and hormones are shifting. Studies show postpartum dyspareunia affects over 50% of women in the first weeks after delivery. But severe pain, pain that lasts for months, or pain that makes penetration impossible deserves evaluation and support — it is not something you simply have to accept.

Why does postpartum dyspareunia happen?

There is rarely one single cause. Breastfeeding (which suppresses estrogen), vaginal tearing and scar tissue, changes in pelvic floor muscle tone, fatigue, stress, and hormonal and psychological factors can all contribute — and they often overlap. Even a cesarean delivery is not fully protective.

How long does postpartum dyspareunia last?

Recovery timelines vary significantly. One study found 31% of women experienced dyspareunia at 3 months postpartum and 12% still experienced it at 2 years. Persistent pain is a reason to look more closely at the cause and build a treatment plan — not to simply wait longer.

Can postpartum painful sex turn into vaginismus?

It can. If the body begins to anticipate pain with penetration, pelvic floor muscles may tighten automatically over time — making insertion feel increasingly painful or impossible. This is one reason postpartum dyspareunia and vaginismus can overlap, and why early treatment of postpartum pain may help prevent the pattern from becoming more entrenched.

How is vaginismus diagnosed?

There is no single definitive test. Diagnosis is based on patient history, reported symptoms, and physical examination. A vaginal exam is not required to confirm the diagnosis under current guidelines — so being told “everything looks normal” does not rule out vaginismus.

How is dyspareunia diagnosed?

Diagnosis typically starts with a detailed conversation about your symptoms — where the pain is, when it happens, what it feels like, and how long it has been going on. A pelvic exam and sometimes urine or swab tests can help identify specific causes. Dyspareunia is a symptom, not a final diagnosis, so the workup focuses on identifying the underlying cause.

When should I see a healthcare provider about painful sex?

Any pain with sex that is severe, ongoing, worsening, or making intimacy difficult deserves evaluation. Painful sex is not something you have to simply accept — and identifying the cause is the first step toward effective treatment. A gynecologist, pelvic floor physical therapist, or sexual health provider can all be good starting points.

When should I talk to a healthcare provider?

You should consider medical evaluation if the pain is severe, persistent, new, emotionally distressing, associated with bleeding, or makes penetration feel impossible. A clinician can help determine whether the main issue is menopause-related dryness, pelvic floor dysfunction, tissue or skin changes, infection, or another pelvic health condition.

How do I talk to my doctor about sexual pain?

Try approaching it the way you would describe any other type of pain: where it hurts, what it feels like, when it happens, how long it has been going on, and whether anything makes it better or worse. Writing these details down before your appointment can help. Your symptoms are valid, and a provider who takes sexual health seriously will want to know.

What are the treatment options for vaginismus?

Treatment is tailored to the individual and often involves a combination of approaches, including pelvic floor physical therapy, cognitive behavioral therapy or sex therapy, vaginal dilation therapy, and in some cases Botox. Most women do best with a multimodal approach.

Is vaginismus curable?

Yes. Clinical studies show that vaginismus symptoms can be fully resolved regardless of severity or cause. With the right combination of treatment and support, most women are able to break the cycle of pain and achieve comfortable penetration.

How long does treatment typically take?

Treatment timelines vary based on severity, consistency of practice, and the combination of therapies used. In a recent clinical study of Milli users, 85% made measurable progress toward intercourse within 90 days, and most women who practiced regularly noticed meaningful change within 3 months. Consistency is the single most important factor — progress depends on sustained, gradual practice over time rather than intensity in any one session.

Are vaginal dilators the only option for painful sex after menopause?

No. Painful sex after menopause may also improve with lubricant, vaginal moisturizers, pelvic floor physical therapy, and local estrogen or other menopause-focused treatment. Most women do best with a combination of approaches.

When should I consider pelvic floor therapy after childbirth?

Pelvic floor therapy may help if you have ongoing pain with penetration, pelvic floor tightness, scar discomfort, difficulty relaxing during sex, or symptoms that are not improving with time. A pelvic floor physical therapist can assess your specific situation and guide both in-clinic and at-home treatment.

Can pelvic floor therapy and dilators be used together?

Yes. For people with pelvic floor tightness, vaginismus, or pain with insertion, pelvic floor therapy and dilators are often used together because they can support relaxation, gradual exposure, and improved tolerance to penetration.

How do dilators help with vaginal tightness?

A common approach to treating vaginismus is to expand, stretch and relax the pelvic floor muscles through vaginal dilators. Just as there is not a one-size fits all solution to treating vaginismus, there is also no one-size fits all dilator. That’s why we’ve developed Milli, a unique vaginal dilator tailored to fit your unique vaginismus needs.
The goal of any dilator is to slowly desensitize your body to increasing degrees of vaginal penetration. Dilators gradually prepare your vagina for penetration. They expand, stretch and relax the pelvic floor muscles. Dilators help reduce the fear and anxiety associated with vaginal penetration, which can in turn help your pelvic muscles relax and break the cycle of pain.

Aren’t all dilators the same?

Just as there is not a one-size fits all solution to treating vaginismus, there is also no one-size fits all dilator. That’s why we’ve developed Milli, a unique vaginal dilator tailored to fit your unique vaginismus needs.
Milli offers several advantages over traditional static dilators, including:
Expands one millimeter at a time

• No intimidating jumps in sizing
• No need to reinsert to adjust size – Avoid discomfort or inconvenience
• All-in-one device – Discreetly fits into your life
• Only OTC cleared vaginal dilator on the market

Are all dilators safe to use?

While the FDA regulates dilators as medical devices, not all companies selling dilators have gone through this rigorous process with the FDA to ensure their products are safe and effective. We recommend you confirm FDA clearance prior to purchasing dilators for any medical use. Milli is the ONLY dilator cleared by the FDA that is available directly to consumers over the counter.

Can vaginal dilators help with painful sex?

Dilators can help when pelvic floor muscle tightness or vaginismus is part of the picture. They gently reintroduce penetration and retrain the body’s response to insertion over time. Dilators are not a treatment for painful sex from other causes — such as infections, skin conditions, or structural issues. Milli is an FDA-cleared vaginal dilator indicated to help relieve the symptoms of vaginismus and related painful sex; it is available over the counter, without a prescription.

Can vaginal dilators help if menopause caused penetration pain?

Yes — they can help some women, especially when menopause has led to pelvic muscle tightness, discomfort with insertion, or a cycle of tension and avoidance. They are often most helpful when used gradually and combined with lubricant and other supportive care. They are not a substitute for medical evaluation when symptoms are severe or new.

Can vaginal dilators help with postpartum painful sex?

Yes, particularly when symptoms overlap with vaginismus or pelvic floor tightening. Dilators help gently reintroduce penetration and retrain the body’s response to insertion over time. In a recent clinical study of Milli users, 85% made measurable progress toward intercourse within 90 days.

Do I need a prescription to start dilation therapy?

No. Vaginal dilators, including Milli, are available without a prescription. That said, speaking with your healthcare provider or a pelvic floor physical therapist can help you develop a plan that addresses the full picture — including any hormonal, structural, or psychological factors that may be contributing.

What is Milli, and how does it work?

Milli is an FDA-cleared expandable vaginal dilator designed for gradual progression. Its small 15mm starting size, smooth silicone cover, and optional vibration make it a gentle and adaptive choice for addressing vaginal tightness related to vaginismus and painful sex. It expands in 1mm increments within the vagina — no removal or reinsertion required — at a pace entirely controlled by the user.

Is Milli suitable for someone with vaginismus?

Yes. Milli is an FDA-cleared vaginal dilator indicated to help relieve the symptoms of vaginismus. Its gradual, patient-controlled expansion and optional vibration are specifically designed to make dilation therapy more manageable for women with vaginismus. In a recent clinical study of Milli users, 85% made measurable progress toward intercourse within 90 days.

What makes Milli different from traditional dilators?

Unlike traditional dilator sets with fixed sizes, Milli is adjustable. It allows you to gradually expand size without needing multiple tools and without the size “jumps” that research links to high discontinuation rates — 41% of static dilator users stop by 3 months and up to 57% by 6 months. Milli keeps you in control of every millimeter of your progress.

Why does Milli match the body’s natural shape?

Milli’s design reflects the natural flexibility of the vaginal canal, which expands from roughly 17mm at the opening to around 45mm toward the back. Its 15–40mm expansion range sits within this natural anatomy, allowing for gradual, comfortable progression that mirrors the way the body is designed to work.

Does vibration actually help with dilation therapy?

For most Milli users, yes. In the clinical study, 80% used Milli’s vibration feature at least half the time, and 57% reported reduced anxiety related to sex at 3 months. Vibration is thought to help relax pelvic floor muscles during insertion, making the experience feel more manageable and less clinical.

What results do Milli users typically experience?

In a recent clinical study of Milli users, 85% made measurable progress toward intercourse within 90 days, 57% reported reduced anxiety related to sex at 3 months, 68% reported more comfortable intercourse at 3 months, and more than 85% stayed on track with recommended use at 6 months. 80% used the vibration feature at least half the time.

Is Milli available without a prescription?

Yes. Milli is an FDA-cleared medical device available over the counter — no prescription required. It is designed to be accessible and easy to use at home, independently or alongside pelvic floor physical therapy.

How do I prepare my Milli before a session?

Make sure your Milli is fully charged and cleaned, then apply water-based lubricant generously to the wand. Avoid silicone-based lubes – they can damage the soft silicone on your device.

What position should I use during a Milli session?

There’s no single “right” position. Many people start semi-upright with feet together and knees apart and use pillows for support. Side-lying or fully reclined with knees apart can also work well. Choose what feels most comfortable.

What size should I start at, and how do I expand?

Begin at Milli’s minimum size (15mm) in a comfortable position. Use the + button to expand 1mm at a time, at your own pace. Pause whenever you need to and watch your progress on the digital display.

How do I help my pelvic floor relax during a session?

Set up a calm space – dim lighting, soothing music, or a guided audio session can help. Try a warm bath or shower beforehand. Milli also has built-in vibration you can activate to help your muscles relax.

How should I clean and store Milli after a session?

Clean the wand with mild soap and water; wipe the handle with a moist towel. Do not submerge or use harsh cleansers. Dry it completely, then return it to its charging case.

Do you offer free shipping?

Yes, we offer free shipping on all orders. Orders will be shipped within 2-3 business days.

Do you deliver internationally?

We do not offer international shipping, as Milli is a medical device and only has market authorization in the US.

What is your warranty and returns policy?

Due to the use and nature of our product, we do not accept returns. Milli comes with a 1-year warranty. For details, see the warranty page.

What is an HSA or FSA?

An HSA (Health Savings Account) and FSA (Flexible Spending Account) are tax-advantaged accounts you fund with pre-tax dollars to pay for qualified medical expenses. Most are offered through your employer, and they typically come with a debit card you can use at checkout for eligible items — like Milli.

Is Milli really HSA/FSA eligible?

Yes. Milli is an FDA-cleared vaginal dilator indicated to help relieve the symptoms of vaginismus (pelvic muscle tightness) and related painful sex. It is a qualified medical expense under HSA and FSA guidelines.

What is Flex, and why is Milli using it?

Flex is a payment platform that lets brands like Milli accept HSA and FSA debit cards directly at checkout. Flex confirms eligibility behind the scenes so you don’t have to track down paperwork or file a claim later. It’s the simplest, most reliable way to use your HSA/FSA on Milli.

What is a Letter of Medical Necessity (LMN)?

A Letter of Medical Necessity is a brief document from a licensed clinician confirming that a product or service is being used to treat a specific medical condition. Some HSA and FSA administrators require an LMN for “dual-use” healthcare items before approving the expense as eligible.

Do I need a Letter of Medical Necessity to buy Milli?

No — not when you check out with Flex. Flex confirms eligibility automatically at checkout, so you don’t need to track down an LMN before you buy. If your HSA or FSA administrator later asks for one (for example, during an audit), Flex can guide you through a brief chat-based telehealth consultation to generate one. Either way, you don’t need to gather paperwork upfront.

What if my HSA or FSA card is declined at checkout?

The most common reason is insufficient funds, since HSA/FSA cards are debit cards. Check your balance with your account administrator. You can also choose “Flex | Pay with HSA/FSA” at checkout, pay with a regular credit or debit card, and submit the itemized receipt Flex emails you for reimbursement.

What happens to my FSA funds at the end of the year?

Most FSAs are “use-it-or-lose-it” — unspent funds may be forfeited at year-end (some plans allow a small carryover or a short grace period; check with your administrator). Putting your FSA balance toward an FDA-cleared medical device is one of the smartest ways to use it before you lose it.

Will buying Milli with my HSA/FSA show up on my insurance?

No. HSA and FSA accounts are separate from your insurance plan. Using them does not create an insurance claim, and your purchase is not visible to your insurance provider. Milli is not reimbursable by insurance.

How do I access the Milli Vaginal Dilator through the VA Prosthetics Sensory Aid Service (PSAS)?

Visit a VA provider and request that they determine that a vaginal dilation is medically necessary to support your healthcare treatment plan. The VA provider submits a consult to PSAS. (Psst, we can show your provider how to complete the consult).

What can I expect?

After we receive and validate the order from the VA, your Milli Vaginal Dilator is ready to ship! We ship the device in a discrete package directly to your home.

What’s the expected out-of-pocket cost?

As a veteran receiving health services within the VA system, you have no out-of-pocket cost. At an appointment with your VA provider, ask for the Milli Vaginal Dilator by name. To qualify, the order must be placed through a VA prosthetics department.

How is the Milli Expanding Vaginal Dilator covered through the VA?

PSAS ensures you receive the prosthetic needs designed to tackle unique challenges — including the Milli Vaginal Dilator for vaginismus and related painful sex.
