Welcome to the board Cumfun. It's always good to see another person posting!

That's an interesting story about your dad teaching you how to masturbate, and watching your brother do it. I hope he never really touched you in a bad way when you were younger. Kinda weird. But anyhow, I don't judge.
As for how my fetish started... This particular fetish just started because my ex boyfriend mentioned it to me, and me always being up for trying new things tried it, and liked it. It's not my favourite fetish, but it is a fun one. I've always been into different things, fetishes and stuff. I don't really know why, that's just the way I've been since I was pretty young. I used to watch porn when I was in elementary school, and always found it so interesting. When I got older I found different types of porn and it really expanded my mind into thinking about all sorts of different fetishes.
I know exactly what you mean about how it's like liberating being able to tell people things about yourself online. It's like the only place you can be completely open about yourself.
Anyway, I think I took up enough space in this thread already. So welcome again.
