That's absolutely horrible man, I'm sorry that happened to you.

I had something a little similar happen to me. My friend who I lost my virginity to accused me of raping him. He identified as straight and we were fairly decent friends. We were both around 15-16 and it was the night of our semi-formal. We were back at another friend's house and had shared a bottle of vodka, we were all incredibly drunk. Our other friend went to bed and we shared a fold out couch. We stayed up talking shit like teenage boys do and then things got around to talking about sex. He eventually said that we could fool around if I wanted to. Of course I did, and we did. We sucked each other off and he even fucked me a little bit. It was my first time and I wasn't too certain of the mechanics of bottoming so I'm pretty sure he was mostly dry humping my ass but there was a bit of penetration.

It was fun, I enjoyed it but naturally we never talked about it again. I never mentioned it to anyone really, I think at most I had hinted I'd done stuff to friends but never who with. They knew I was into guys though. This was until one of my friends accosted me at school one day claiming that I had raped my friend. She said he was saying that I forced him to do things with him. I was absolutely shocked. I explained that we were both drunk and that he was the top and I had no idea how I would have even gone about forcing him to do anything. It was a pretty fucked up thing to do, try and convince someone that your first time wasn't you raping someone.

No one else ever really mentioned it to me. Needless to say, the friendship was pretty damaged after that. We only ever hung out in group settings after that, never really alone. There was an interesting incident at a party years later, but that's not really relevant.

I'm sorry you went through this man, getting accused of this stuff by someone you consider a friend and put trust into truly does hurt and I wish it didn't happen to you.
