How do you tell a guy to leave?

So I’m what the boys would call “easy”, I usually have sex on the first date if it’s planned beforehand (we’ve been talking for a while) or the guy is mean or boring but really hot (I don’t plan to see them again). Buuuut a lot of the times I have guys over they just don’t wanna leave. How do I get them to leave without sounding rude?
