I'm 22 years old and have never really been sure if I had experienced an orgasm. I've heard that you'll know when it happens, but sex has been, for the most part very pleasurable and enjoyable thus far so that wasn't helpful at the time. So I thought maybe it was happening every time, but ohh wow, was I ever wrong. It definitely finally happened. I found myself at work the entire day after with this urge to just tell everyone I came in contact with. When did it finally happen for you?
