Sex doesn’t
have to hurt
Painful sex is quite common, but it’s not normal. One cause is a penetration disorder called vaginismus, or vaginal tightness.

You are not alone
Studies suggest 5-17% of women experience vaginal tightness—a condition that causes the vaginal muscles to contract involuntarily—making penetration of any kind painful or impossible.1
We’ll help you find the answers you need to claim your sexual health:

Milli is the first and only all-in-one vaginal dilator that gradually expands the vagina at a pace you control, helping prepare your vagina for penetration.

You’re in control
Unlike static dilators that may have intimidating jumps in sizing, with Milli you can gradually expand and easily monitor the pace of dilation one millimeter at a time.


Not all dilators
are created equal
Milli, the only all-in-one expandable vaginal dilator, offers several advantages over traditional dilators.
