Don’t invite him in.
OK, this is a bit obvious, but if you don’t invite the guy in, you won’t sleep with him. It’s as simple as that. So, if the two of you are outside your door having a good night game of tonsil hockey, fight the temptation to invite him in. Tell him the place is a mess, or you’re tired, or you’re roommate is a pain in the ass (even if you don’t have one) or that your apartment is a crime scene. Whatever.

Because once you invite the dude in, he’s looking for the green light for sex. “I’d be checking for contraceptives,” says Sean, 31.

Say hello to your electric friend.
Before a big date, many men swear by an important ritual. They spend a little time alone and… uhhh, clean out their pipes, if you know what I mean. That way, they’re more relaxed and can behave like a civilized person. I don’t pretend to be an expert on the inner workings of women’s plumbing, so to speak, but if you’re wound up but don't want to have sex on a first date, why not spend a little quality time with yourself? Maybe invite your electric friend over for a get-together before you go out.
