Most Helpful Guy
Tough to say. He might be obsessed, crazy or yes, the sex could have been so good from his perspective that he's trying to get more of it. If it really makes you uncomfortable, change your contact info and take steps to see he doesn't get it. If he still persists and you can't get him to stop, get a restraining order. If it's more of an amusing annoyance, just assume that yes, you were THAT good, and be flattered by it. If you don't want him, though, don't put up with his BS.
