#2 Singles only. Please, please, please only go looking for a one night stand if you’re single. It’s not cool to cheat, and you’re putting the person you go home with in a very bad position that they probably don’t know they’re getting into. It’s only okay to have one-off sex when you’re free to do it. If someone’s going to get hurt when you sleep with your one night stand, you should probably double check your priorities.
