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?

Since orgasms cause a release of endorphins into one's cerebral-spinal fluid and endorphins are also somewhat responsible for the emotion of happiness, etc., is it possible that excessive masturbation and/or intercourse would lead to a depleted level of endorphins in the system that could in turn cause one's affect to become somewhat "flat"? Could a sustained low level of endorphins in the system induce depression and/or mood disorder?

I have a somewhat embarrassing question. Is there anything specific I can do in my diet or anything to where my PMS bleeding flow isn't so heavy? It has been so heavy that at times, I put a tampon in and in a matter of like 20 min, I have to change in the beginning of my cycle. I also have had it leak into my clothing. This can be quite embarrassing. Any help would be appreciated.

I visited a doctor, and he told me I had a very large tesicle, what is producing this? Is it dangerous?

My boyfriend has genital warts, but he is very afraid of giving them to me. We were wondering if there was a condom that also covered up the scrotum. We ask because he was told that, even with a condom, he could still transmit the disease if his scrotum came in contact with my vagina. Please help.
