When you start with an extra small dilator and can insert it, move it, do self stretches with no to low pain - then the brain starts to realize that "ok, that wasn't so bad" and the secondary response of muscular tensions ease, allowing for less pain. Scanning and mapping the pelvic floor alongside your dilator use also helps the brain perceive these muscles in a more normalized way. This allows for much less "red flag signals" being sent to the brain. Your overall confidence level with repeated successful sessions with the dilator and vaginal canal mapping allows you return to intercourse with low to no pain. So essentially what you are doing is changing the perception in your brain about the health of your vagina and decreasing the sensitivity of the nervous system to keep muscle tension in check.
Along with dilator work there are other exercises such as flexibility work to the hips and trunk and relaxation breathing to quiet the nervous system. It is important that during this process you abstain from sexual intercourse. But of course this is not to say that you abstain from intimacy. We strongly recommend the personalized training of a women's health physical therapist to guide you. You can also use these and other techniques taught in our DVD guide under the consultation of a health care provider.
*Be advised that some conditions such as Vulvar Vestibulodynia (Vestibulitis) may need further medical management before beginning the use of dilators.
