I can’t ever have guy friends...

A few months ago, my friend drunk snapped me in the middle of the night of him doing some kinky masturbation. I always though he kind of liked me, but he has a girlfriend so I just ignored it. Today he was telling me how him and his girlfriend are in an open relationship.. once again I kind of changed the subject. We hung out for about 3 or so hours just chilling in his car and he was telling me he liked me wearing tighter shirts and making all these sexual compliments and stuff. The sexual tension is real. I’m kind of weirded out but I don’t know how to tell him that. He talks to his girlfriend about me a lot, and I met her the other week and apparently she’s threatened by me and doesn’t like how attractive I am lol. Well... I don’t know what to do in this situation. This literally happens with every guy I become friends with.
