>>9371490>Anyone here well versed in the origin of fetishes?
Actually I am, or at least I know enough to know it's deeply personal. Two people could have the same fetish and get off on it for entirely different reasons. I have a sneaking suspicion that there's a genetic component to dominance/submission in the bedroom, just based on what my dads told me about his sex life. That and the fact that I was always submissive even before puberty. I have fond memories of being buried in the sandpit in early primary school by two girls, and then they poked me through the sand with sticks. They also dug a big hole around my crotch and were threatening to poke there. Also I recall enjoying laying in beanbags with other beanbags on top of me and letting the other kids jump on me.
Anyway, I don't believe these things were the origin of my submissive behaviour per se, but rather being submissive sexually was always just an inherent part of my makeup. The same (probably) applies to you. As for how you get turned on by that specific fetish, who knows. That's not something any random stranger on the internet could tell you. It doesn't do too much for me cause my penis is about the same length which I know is perfectly fine.
