Milli Expandable Vaginal Dilator

Treat penetration pain with the only adjustable dilator for vaginismus
Regular price
Unit price


If you experience pain with vaginal insertion—whether during sex, at the OB/GYN or simply when using a tampon—you may have vaginismus, a condition that causes the pelvic floor muscles to tighten or spasm involuntarily.

Vaginal dilators offer a solution by gradually stretching and relaxing the muscles to prepare them for penetration. The problem? You'll need to purchase several—and insert and remove them repeatedly as you find the right fit and progress to larger dilators over time.

There is no one-size-fits-all dilator—except for Milli.

Milli is the only vaginal dilator that you can adjust while you're using it, one millimeter at a time. Once Milli has been inserted, simply use the plus and minus buttons on the device to change its diameter, without the discomfort and hassle of removal.

Static dilators often have sizable differences in diameter, which can cause discomfort when advancing to the next level of dilation.

Milli allows you to control the pace of your treatment as you reclaim your sexual wellness. It also offers two vibration options, adding benefits of relaxation and even pleasure.

Milli spans the size range offered by most dilator sets on the market, starting at 15 mm (just over a half-inch) to 40 mm (slightly wider than the average penis diameter of 37 mm). The device comes with a portable case that's rechargeable via USB.

Milli is an FDA-cleared medical device intended to relieve the symptoms of vaginismus. You may have vaginismus if you have had any of the following symptoms for at least six months and they cause significant distress:
• Tightening of the muscles inside the vagina, making vaginal sex not possible
• A presence of pain (also called dyspareunia) or burning when trying to have vaginal sex
• Not wanting to have vaginal sex because of the pain or expected pain
• Avoiding vaginal sex because of the expected difficulty due to vaginal tightening and/or spasm
• Severe fear of vaginal sex or the pain associated with vaginal sex

How to Use

Lie on your back and use gentle pressure to insert Milli into your vagina, using a water-based lubricant if desired. It may be easier to insert if the tip is pointed slightly toward the tailbone.

While Milli is inserted, slowly adjust the dilation to your comfort. The plus and minus buttons on the device change its diameter, one millimeter at a time.

If you feel resistance or a sensation of tightness or pressure, pause and determine whether it is uncomfortable or painful. If needed, pull Milli out closer to the vaginal opening until you reach a place where you no longer feel discomfort. You can also rotate Milli if you are feeling pressure on your urethra.

Remove Milli in its dilated state or, if preferred, retract the device to the setting of 0 before removal. Note the dilation setting achieved during treatment to track your progress.

Milli recommends using the product for five to 20 minutes per session, three to five times per week. Repeat treatment until your desired setting can be achieved.

Clean the wand portion with soap and water before each use, and wipe the handle with a damp cloth. Do not submerge Milli underwater.
