Does it only last for days? I have been hooking up with one guy for more than a year now but we've only had sex 4 times because we don't live in the same city. It started out as a random make out session when we met at a bar over a year ago. I honestly thought I would never have to see him again after I slept with him I slept with him the second time we went out, not the night we met. But it turned out that we still talk after the first time we had sex so we kept in touch. How long can it last if neither of us start seeing other people?
