Replying to Need advice on hook ups

So I'm on spring break n' I was out at the bars last night spitting mad game. I was totally making on this one chick. Perfect 10/10. She started to crab my crotch and make out with me, ya know, baller shit. Then she started to ask where I was staying and if she could see my room so i knew she was DTF. It's getting late so I'm ready to go slam. So I paid my tab and went home and fucked her brother, does that make me gay? I mean they're twins so they sort of look alike.
