Well I cant deal with it anymore, I love my gf with all my heart but she is really persisiting on having sex. Last time we had sex was about 5 months ago, I stopped because i am really really worried about getting her pregnant. Se wont take the pill as most know, due to saying that it may give her cancer of the uterus which runs in her family. I told her it helps with cancer, but she will not believe me. Im afraid to lose her and dont want to make her upset, but ill admit im not man enough yet to raise a kid, so i dont think im ready for sex even at the age of 24 almost. Anyways if I decided to have sex, which is the SAFEST way to prevent pregnancy. Condom that have speramacide, or do i buy extra spermacide, like do they sell it in a tube? And then put it on the outiside of the condom? Any help is well appreciated.
