As simple as it sounds. Sometimes our kinks are mysterious, but sometimes you can look back and see a clear origin for them, whether that be a traumatic response or a childhood hobby or something.
For me? While figuring out my bisexuality, i also played a lot of fighting games.
Seeing two female characters throw each other in Soul Calibur or Dead or Alive was one of the earliest examples of female physical contact that i got that my parents didn’t immediately try to ban so like… it stuck with me and now as an adult i get turned on by certain kinds of fights or martial arts gear.
Alas, I am mostly kinkless.
I can play around with most things if a partner has a kink, but the closest I come to a real kink is fancy underwear. Not even specifically kinky underwear like crotchless panties or whatever. Just pretty panties and bras in women.
I get more thrill from that than outright nudity by itself. Didn’t when I was younger, they were both very much arousing, and in equal measure. But I worked as a nurse’s assistant and took a lot of art classes, so nudity lost the ability to be arousing by itself. There has to be a sexual connotation to the notify nudity for it to flip the switch for arousal instead of just curiosity or appreciation.
But, I can indeed trace that enjoyment to a single event.
Way back, and I won’t mention specific ages because people are assholes, but when I was young; I had only seen the usual panties that you might run into as a kid. Plain cotton, nothing beyond maybe a wonder woman symbol, or my mom’s, which was not a sexual thing for sure lol.
But as puberty was coming along, I had a brief encounter (puns fully intended) with a young lady that was a bit out of the norm. She had these lacy, bright blue panties on, and (as I discovered a bit later) a matching bra. Who knew girls could have cool underwear like that? I didn’t! I hadn’t run across playboy or the like yet, and had never paid attention to the women’s section of catalogs when flipping through such things.
This eye opener made me very much enjoy seeing girls in their underwear, and made it something that was awesome in itself rather than as a sign I was about to enjoy more than that.
But, it isn’t a fetish level thing at all. I don’t require it to enjoy sex, and It’s only when someone I’m interested in is wearing them that it matters. An established partner can walk in naked and my mind doesn’t immediately turn to sex. But let my wife walk in in her fancy panties? Oh yeah, I’m happy and hoping it can turn into sex. It usually does lol, she knows I enjoy it, so it’s usually a sign she’s up for fun to begin with if she’s showing off.
But that first girl? Despite it being a one time thing, I can remember every second of it, including the way my fingers rasped over the blue lace. Full sensory memory there.
