Why do my boyfriend's balls move on their own?

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?


How many times a day do people typically get erections?

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?


Can I prevent erections or make them go away?

I am a male who experiences a lot of spontaneous erection. It's almost comical. My problem is that I model nude for art classes and have difficulty preventing or getting rid of my erection. The whole thinking about something else idea never works for me. I was wondering if you could tell me of a cream or something I could use to prevent an erection or possibly make an erection go away. I've tried the usual muscle and arthritis creams, but those don't work. I can still get an erection anyway. Is there something that numbs for a period of a few hours that I could use? I thought of using some desensitizing creams you can find at adult stores, but didn't bother trying them because I figured they're designed to help you keep your erection, not lose it. It would be very helpful if you could help me out.


Why am I getting erections so frequently?

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?
