So here's a weird one..
When I was fresh out of uni, I met this really hot guy in his 40s and we hooked up a few times. Fast forward to when I turned 30, i moved to a new city and randomly came across him on the app again, so i sent him a message. We hooked up, he still looked hot af, and somehow it turned into more than just a casual thing. We started hanging out more and actually got to know each other. Yes he had been married for about 20+ years before started fooling around with guys and ended up separating from his wife.
One night we were just talking about life and stuff, he was telling me about his ex wife and the kids. And then casually mentioned about his gay identical twin brother and had always secretly felt a bit jealous that his twin brother was having amazing sex all the time.
All this time I genuinely thought I had reconnected with the same dude i met years ago, so i told him the story. He pulled up photos of his twin brother and they looked exactly the same (both were equally hung). I was shocked, we started laughing, had a few glasses of wine and more seggs afterwards.
