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?

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?

I've heard so many horror stories of women who wait until their mid-thirties or later to have children, then find out that they are infertile. I'm 25 years old now and nowhere near getting married or having babies, yet I don't want this to happen to me when I'm ready. What can I do now to protect my fertility and make sure I am able to conceive when the time is right? It's causing me a lot of anxiety!!

1) I have seen multiple advertisements for egg donation in my school's newspaper. I could sell my eggs for $25,000 or more! That's a year of tuition! There's got to be a catch. When I do some research to find out the procedure and the risks, I only seem to find oocyte donation "businesses" — not the most straight forward sources on the subject. Alice, I trust you! Can you tell me... what have I got to lose?

2) I see lots of ads in the paper here at my school about egg donors wanted. I think that I would like to donate an egg, but I can't find any information on the net about donating — only about receiving a donation. Can you tell me what the process is like, how long it takes, and whether there are side effects or permanent long-term effects? Or point me towards some other resource.
