I have two specific kinks whose origins I think I can trace, @Tigre_Bigotes
The first one is my scent fetish. I am turned on by male scents, such as smelly armpits, sweaty balls and crotch, musky holes, sweaty feet: I always ask my dates or hires to not wear any perfume or deodorant, and even to not shower before we hit the sack. In some cases, it gets to the point of requesting them to not change their underwear or socks for a couple of days before, to build more scent. It might sound weird, but I know that I am not alone: there is a long thread on this kink in the Fetish section of this forum.
I have figured out that this comes from my first-ever male sexual experience, which happened with my best friend when we were both 15-16. He had a kind of strong teenager body odor, and it became associated with the thrill of being close to him (I had a fierce crush on him), and with the pleasure I felt touching him and sucking his dick.
My second traceable kink is cum: I learned to enjoy its very particular flavor by swallowing it to avoid a mess when masturbating. The rest is history.
