Of course it is unless you are using A condom your girl is taking pills moron! Just kidding. Don't you know anything about sex?
Sorry, but it is still effective. Unfortunately for everyone, a female can get pregnant when he, she or both people are drunk. Don't drink and use a condom when having sex. Do it for the rest of the world.
YESSSS any sperm is effective unless you have a disorder.. So use condoms drunk or not lol
