My boyfriend has suggested "tit sex" as an alternative to intercourse, which we want to wait a while to go ahead and do. I want to know, what exactly is "tit sex" and how do you do it? Will it hurt?

1) It seems that I can't maintain an erection for more than a couple of minutes during intercourse. In fact, sometimes it doesn't seem to want to get up and play at all. The girlfriend is really starting to take this personally, but I know it's not her fault. Help! Are there any vitamins, diets, etc. that may help?

2) To put it very simply, I am having trouble having erections for a while now. I used to be able to. I can't have them at all, during intimate encounters or during masturbation. I get a little "hard" but cannot get completely hard. Could you please help me? Thank you!!

I keep seeing this fetish all over the internet. What is sexual/erotic hypnosis? Is there somewhere my partner and I can learn how to do it to each other, or online?

My roommate and I were wondering whether or not there was a difference in sleeping with a man with an uncircumcised penis or one that has been cut? My roommate's current boyfriend is uncircumcised and she has heard horror stories about sleeping with men that have uncircumcised penises.

My boyfriend likes to wear my underwear. Not just before we have sex, but just all the time. He's not gay or anything, he says he just "likes the way it feels." Is this normal? Is it something that all guys go through? Should I be worried? It doesn't bother me. I actually kinda think it's sexy, but I was just wondering if there was something else going on?
