How do I get rid of this gay guy?

So I've been friends with this guy for years, and I thought he was just nerdy but he's just really gay. I get teased by my friends for hanging out with that guy. At first I didn't notice anything strange but after reassessing the whole situation, and just getting hints with things he has said, I figured that he's one of those kind of people who are males and likes penises (possibly in his butt).

All jokes aside, I don't want to get rid of the guy because of the mere fact that he's gay. He actually had the idea of me moving out with him in a foreign country (will not name it due to privacy reasons) which is making this even more awkward.
