They were centered around my fetish. I remember imagining black rubber gloves and various medical treatments. I've always had an active imagination and liked thinking up stories. Didn't have any idea that those were different until much later.

I don't remember what my very first fantasy was, but a lot of my earlier ones focused on oral sex, possibly because the first porn video I ever saw was largely about oral and I'd never really fantasized before seeing it. It would be a lot time before the idea of being penetrated was even remotely sexy to me.

I think my first real fantasies would be about female classmates in middle school. Just have dreams of them, my mind would run wild.
