I had unprotected sex with my girlfriend 2 days after her periods was over, as she told me that 10 days after period are safe to have unprotected sex. Her last period was 27th October. Well today, 19th November, she called me and said that her period repeats in 20-25 days and she should have period now but she is not having. Can you tell me the reason? Another question, is that safe to have unprotected sex after period within 10days? Please mail me answer, also fast please.

I have been on the pill for over 2 years, and have never missed a pill. I just started my inactive pills on Sunday of this week, and had sex with my boyfriend on Monday. He wore a condom but I am still concerned there is a chance I might still get pregnant. Is it possible for this to happen or am I safe?

I am a virgin and naive to many things concerning sexuality. I have a boyfriend now and am curious. Can you tell me how a women's ovulation cycle works? How do I know when I am ovulating? During what time of the month will sex be the most painful?

I am also wondering if certain sports can affect first sexual interncourse. I am a dancer, which means I do a lot of stretching. Can this sort of physical activity wear away my hymen? As dancers, we also have the tendency to clench our butt muscles. Can the tightness in these muscles affect sexual intercourse?

I always get a sticky white goo in my pants, when I wipe it off it sometimes looks abit yellow. It doesnt itch, smell or I dont suffer from any pain with it. What do you think it is, and who do you think i should see about it?
