A member asked:

How much semen does it take to become pregnant? i have accidentally partially ejaculated on my gf's vaginal opening, maybe a drop. whats the risk?

Depends on Her cycle: If your girl friend was in the fertile period of her cycle, a tiny drop of semen may cause pregnancy. Condoms prevent any sexually transmitted diseases as well as pregnancy.

Depends on situation: Of every 100 women whose partners use the "withdrawal method", 27 will become pregnant each year if they don't always do it correctly. Pregnancy is also possible if semen or pre-ejaculate is spilled on the vulva. - See more at: http://www.plannedparenthood.org/health-info/birth-control/withdrawal-
