A Hot Shower After Sex Can Prevent Pregnancy
There are a lot of innovative ways people think of to avoid pregnancy. Showering and peeing after sex are not effective contraceptive methods. Hundreds of millions of sperm are released in ejaculate and baby making requires only one. It's simply not possible to get all the sperm out of there through washing. As for peeing, urine doesn't come out of the vagina (it's a different hole) – but peeing after sex can help some women avoid painful urinary tract infections. Pulling out is also ineffective because pre-ejaculate may pick up enough sperm from previous ejaculation to cause pregnancy. Jumping jacks, sex standing up, and sex while she's on her period are no-go's too.
