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?

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!!

My period is late this month, and I'm afraid that I may be pregnant. The weird thing is, though, my partner and I never actually had actual sexual intercourse (in other words, there was no penetration). I'm wondering if the wet environment could still be a risk. I'm hoping that it's due to stress and fatigue with finals coming on that causing this delay. How long should I wait before getting tested?

I have a latex sensitivity, but would like to perform safer oral sex. Are lubricants on non-latex condoms harmful if ingested? I can't seem to find non-latex, non-lubricated condoms anywhere.

I have a question concerning veins on the penis. For a long time now, I have had a vein on my penis which is quite visible. The other day I noticed another vein on my penis that was becoming more noticeable. I know that there are no physical problems with having visible veins on my penis, but I don't like it. What has caused these veins to become more visible and how do I cover them up? I j/o frequently. I know this is a cosmetic problem, but it's an important problem to me. Thanks for your time.

I have been on the Nuvaring for three months now, and I am keeping it in for the four weeks then changing it because my doctor said there's no need for me to have a period. About two weeks ago I started having dark brown discharge and it has gotten more heavy, but only when I run or stand up real quick. Is this normal or should I call my doctor and find out what is going on?

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.
