not a great storyteller but I let my friend fuck me for the first time because I was 20 and depressed i'd never got laid and he was gay and available.

Didn't realise he was a top or I might have backed out. Felt weird having a dick in my ass the first time but hurt less than you'd think. Did it with him a couple more times before we lost touch, did some self-reflection, turns out i'm bi.
