I had sex for the first time with my boyfriend and while the foreplay was nice...his penis is so small that by the end it had slipped off him and ended up in me.  It was the most atrocious thing ever!

My partner loves it when I'm on top, so we take turns. I'm on top first, then he is -- and therein lies the problem. He can't orgasm with me on top. This really bugs me. According to popular belief, that is not normal. Why does this happen with us?
