I am a twenty-one-year-old virgin who has just recently started seeing a girl very seriously. I am frustrated at how my body reacts to the slightest physical stimulus. Holding hands, talking about physical affection, even thinking about kissing gives me an erection. I am not thinking about sex, and we are not going to have sex until we are married, but I can't believe how frequent these erections are. I know it's common for guys my age to have erections, but just being with a girl I care about gives me one, and it's not easy to hide, and I don't want her to think the wrong thing. I used to masturbate and view pornography a lot but I finally stopped because I didn't agree with it. I stopped about the same time I met her. Do you think that my past is causing my body to want something I'm not going to give it?

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?

I ended a relationship about a year ago. I have always seemed to have a yeast infection when I went to doctors before. In my relationship I had went to the doctors before because of discharge and just told them I didn’t need to really be looked at because I know what it is. Well at the end of my relationship I went to the doctor to get a whole check-up. Come to find out that what I thought was a yeast infection turned out to be trichomoniasis. I think I have had it for a couple of years now. I have gone to be treated for it two times. Each time it would go away and then come back. I was wondering if it was because I had it for such a long time?

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!!
