I have a weird question. My boyfriend and I were talking and he told me that men's balls move on their own throughout the day. I did not believe him so he showed me. He got undressed and laid back on the bed and told me to lift his penis and watch real close. I did and unbelievably, his balls moved. It's like they vibrated kind of like a heart beat. It was so cool. What makes a man's balls move alone?

PLEASE, PLEASE, PLEASE answer this question for me. Are condoms you buy from machines in the bathroom safe? What I mean is, could they carry some sort of disease or STD or anything that can make me sick (I don't mean allergies)? And also, could you tell me if American condoms are better than other countries' condoms? I read that U.S. condoms are electronically tested for defects or diseases, but I was wondering if other countries like Europe or Thailand or whatever tested their condoms, too. If I was older, I would buy condoms from boxes, but until then, I am stuck buying them from bathroom machines.

I have a blood disorder (leiden factor V) which prevents me from talking any form of birth control with hormones in it. This is a problem as I am very paranoid about getting pregnant, I would like to have a child at some point, but not for five or six years. Condoms just seem to risky, and diaphragms and female condoms don't work well for me. So I'm not quite sure what to do. I am able to take the plan B pill, and wondered if I can just take it after having sex. Or if there are any other options out there I would love to know about them! Thank you!

How does a man get infected with HIV through heterosexual vaginal intercourse?

I have tested positive for herpes 1 and herpes 2. My boyfriend has also tested positive for herpes 1 and herpes 2. This a a long-term stable relationship. Neither of us has outbreaks very often.

Since this is a monogamous relationship, do we need to use any protection for genital or oral sex? I understand that we both have antibodies for 1 and 2 so I don't believe we can reinfect each other. However, when I consulted some doctors and sites, they suggested refraining from any sexual intimacy whenever one of us has an outbreak or feels an outbreak is about to happen.

My question is: if we both already have herpes 1 & 2 can we a) re-infect each other or b) cause either of us to have more outbreaks? Also, can we spread the virus to other locations on our own bodies?

Thanks, Alice. I hope you can help us.

Help me!!! I've put the condom on backwards when we were drunk and then turned it the right way round. I'm worried about my girlfriend. She is so sweet and kind and does not deserve this. What chance does she have of being pregnant?

Should a normal man's penis become erect for a certain number of times throughout one day (without any external stimulus)? Or, do these erections occur only while a man is sleeping? I have been masturbating once every day or every other day, and I have noticed that I rarely get any of those spontaneous erections during the day at all. Plus, I have been waking up with no morning erection during the past week. Have I been masturbating too much?
