Ok, first story here and not a native speaker so bare with me
When I was 18/19 me and my best friend (code name Clara) had a big big crush on this guy, let’s call him Mat.
He was a really nice guy and extremely hot. He played basketball since he was a little kid so he became a tall and fit dude by the time we were 19. six pack, wide back, firm butt, the whole deal.
We were both virgins by the time we met Mat so we used to fantasize with him being our boyfriend, we would borrow him for our fantasizes because we knew he wouldn’t end his 4 year relationship so it was always platonic
By the middle of the school year I had my first time with a boy and I felt like an empowered woman, like I knew It all, i was always very sexual but after my first time i became obsessed with sex so our made up “boyfriend” fantasies with Mat turned very explicitly sexual and it was now normal to talk about them with my best friend.
