When a guy ejaculates, he gets even harder, so it can hurt a little sometimes. In my experience, he always slows down or stops movement when he’s coming. There’s a very small gushing sensation. But the best part is after he pulls out. Just lay there, it feels like tiny stars exploding inside you. This is, of course, with no condom. Make sure to use another form of birth control unless you want to get pregnant. And make sure you KNOW he doesn’t have any VD.
