    I appreciate you adding the percentage of effectiveness into the video. However I think that some methods (e.g. some birth control pills should warrant more significant digits. 99.9 is still a pregnancy every 1000 times you have sex which for some people is every 3-6 years.

This is a big difference because a lot of people have sex that many times in their lives.

    Anon who has problems with orgasm, I strongly recommend that you give toys a try, if you can. A really good one can help you reach orgasm for the first time, and help you figure out what you like. (Hey Epiphora is a great research on these topics check her blog out).
