Several years ago I posted a personal ad in the fetish section of the magazine "California Contacts" trying to find a play nurse. I did it the old fashioned way, submitting a naked polaroid selfie of myself with an erection, blackened out eyes & nose, & not using email (didn't do computers then) & forwarded snail mail.
Problem is, that at work there was a clique my boss was part of, & one of his friends had a fixation on prostitutes (not to hire for himself, but amusement purposes-- so he claimed). My boss (also a close friend) gratuitously mumbled out to himself (but audibly) that I had a secret. Later on another occasion said to me, "do you know what need?.....a nurse! Yeah, a nurse to give you a nice sponge bath". That remark came from out of the blue, & was said with a smirk on his face.
They apparently figured out that it was me because of geographic location, computer illiteracy, long hair & unblackened visible facial features in photo, etc. But also another element: I had encountered 3-4 weird experiences with medical providers in which I felt bullied, tricked, & "encroached upon" unnecessarily. I had recounted those stories to my coworkers & was obviously upset about them.
Apparently my coworkers found my ad & complaints incongruous, but they weren't. One was a situation of incompetent professionals who were holding the cards & operating entirely by their rules. The other, an ad looking for consensual interaction. No bullying, no hidden agenda. But apparently they perceived me as someone throwing proverbial stones from a glass house.
Here is the issue with getting caught:
It's less an issue of shame than simply not wanting to share my kinks with ANYONE I don't want to act out my kinky fantasies with! Conversely, no one needs to have my proclivities shoved down their throat.
Also, not being within the proverbial norm can make you lose status & cost you your career! As someone who gets regressive ONLY WHEN HORNY, but then goes back to "normal" after shooting hiz wad, I can't say it is a significant aspect of my lifestyle. Of no relevance to 99.999% of those around me.
