I beleive that most of these fine ladies here that you find on Eccie are 'professionals' and they know how to take care of themselves and their business. You should see a lot of the same answers.
Some ladies do use the sponge and swear by it. I 'tested' it with my SO once, and he knocked it loose, causeing a mess, so I won't use it. But perhaps it works great with non agressive sex? I am bloated and feeling ugly at this time anyways, the last thing I want to do is to go out on a date. And with the type of birth control pills I take, I rarely have to deal with it anyways.
Every lady should be seeing her Dr. once a month and getting checked. If she has any sense, then she is...and all of these ladies who have respounded seem to have sense!
