You can get pregnant the first time, the last time, and every time in between. That is one of those famous myths, that you can’t get pregnant the first time, that I keep trying to dispel. Some others are: douching with Coke after intercourse prevents pregnancy. No douche works. Having sex standing up prevents pregnancy. It does not. Using the pull-out method, where the man withdraws his penis and ejaculates outside the woman prevents pregnancy. It does not because there is a droplet of liquid on the tip of the penis before ejaculation that contains thousands of sperm.
