How can having multiple sex partners be a risk factor for cervical cancer? What is the difference between having sex with one man one thousand times and sex with one thousand men (not that I'm planning to!) one time?

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!

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?

1) Is having sex in the shower that is hot or in a hot tub safe? Someone told me the heat kills the sperm. I thought it sounds dumb but I was just wondering.

2) I have a question about sex in swimming pools and hot tubs. Will the chemicals deteriorate a condom? Also, can spermicide be used in water or will it be washed away? Please answer. Thank you.

I have always been attracted to men, and have only been with men. I am currently happily engaged to a man, and have no doubts about our relationship. However, I've discovered over the past couple of years (even when I was with my previous boyfriend) that I do not like porn with men in it. I like lesbian porn! And anytime I've masturbated I've fantasized about women (never one that I know or have seen.) It's made me very uncomfortable, finally admitting it to myself. I do remember when I was in 7th grade there was a new girl at our school. When she got a boyfriend I was very jealous; I just assumed it was because she was new and I didn't have all her attention *ha* Is this normal? Am I out of my mind!?
