My boyfriend and I have had vaginal intercourse before, but he is obsessed with wanting to try anal sex with me. What should I expect? Is it very painful, and can I be pleasured by it? Thank you.

I think I had an orgasm but I am not sure. Can you help me figure it out? My husband and I were making love, I was rubbing my clitoris which when doing so I can usually have an orgasm. I felt what I thought was an orgasm but I did not come on the inside. It lasted a little longer than usual, but I didn't feel any juices flowing.... I didn't fake it because I felt like I was having an orgasm, but after I wasn't wet. Can you explain?
