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?

My boyfriend and I are having sex 2 days after my menstrual cycle. I am on birth control. I finish my cycle on a Saturday and start the new cycle on Sunday. We usually have sex on the Saturday night before I start the new cycle. Is it safe to have sex even though you have finished your menstrual cycle but have not started taking the pill for the next cycle?

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?

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 was wondering if interval training could improve my ability to achieve multiple orgasms in one night. I had a friend who said he masturbated two times a day for three weeks, three times a day for another three weeks, four times a day for three weeks, and so on. He said this improved his stamina. I want to increase my output of semen as well. Any thoughts?

What is oxytocin and does your body produce it during masturbation? I heard you can buy it, but if you do, does that mean you are going to start producing milk at random times for women?

How long to wait for sex after a miscarriage? What if you already had sex too soon after a miscarriage? What will happen if you did?

This may seem a ridiculous question, but here goes. I have a trip planned to Hawaii and just realized that during my vacation time, I am scheduled to be on my period. Needless to say, that will definitely slow down my plans for ocean swimming and loads of tropical sex with my boyfriend. Is there a way to safely alter my cycle by missing birth control pills or other means?
