I've seen a lot of posts lately where women have commented saying that if a man has peed before he's precummed then it means it doesn't have semen in. No this is NOT true. Precum can contain sperm whether he has peed before hand or not! Yes technically there is a smaller chance of you getting pregnant through precum alone, however it is not impossible. If you have not used contraception and do not want to get pregnant I suggest you use an emergency contraceptive, and talk to your doctor about long term contraceptives. I am not saying this to scare anyone, but I would hate for someone to be given the wrong information and end up with an unwanted pregnancy.
