Could be wetting yourself, seeing others wet themselves or both? Could be in clothing, protective wear like pull ups and diapers or bedwetting. I ask because kink forums and dating apps lean so heavily toward BDSM. And even when I find a message board or online community for pee kinks, the lion's share of members are into for very BDSM/control/adult-baby adjacent reasons. Not finding many like me who are just into the body positive innocent curiosity side of it but still with a keen awareness of the inherently kinky sexual overtones. It's also been hard to find someone to do this stuff with. Almost all my GFs liked peeing together or in front of each other. (and plenty of female friends.) But when it came to anything kinky like peeing on each other or self wetting, it's never been something a girlfriend was into and I was so fucking uncomfortable the 2 or 3 times a girlfriend tried to do it just for my sake.
We are heavily into pee fetishes together and with others. Not into adult-baby fetishes though. It is mostly peeing on each other either for pleasure or for dominance in BDSM play. For BDSM play or just for fun we enjoy controlling others to wet themselves in clothing (usually a sexy outfit) typically for exhibitionism/humiliation.
One reason I asked is because I'm so fed up with these fetish dating apps which are all 99% BDSM and people looking for a third or three-ways. The final straw came last night when I downloaded a newer fetish dating app that I expected to have a wider variety of kinks represented in its users. But when I was setting it up, after your name and email, the first question is your kink and the drop-down menu was all BDSM and then a bunch of stuff that are just parts of BDSM, like "top," "bottom," "brat," "submission" and on and on. Then there were options for "fetishism" and "kinkster," which are asinine options for a kink app. Then "unsure." I was honestly so disgusted (and I don't use that word lightly) I deleted the app immediately without finishing my profile.
