@Osamu09 tbh exhibitionism has been bastardised on this site idek what it means anymore [hidden sex] could be (and often is) cheating in private. i think it's a good proposal at least

but isn't it either "hidden sex" or "exhibitionism"?

Damn, I spent like several hours making a proper suggestion for this tag, only to see someone had done basically the exact same thing at the same time. Nevertheless, it's probably a good thing there are like-minded people in this. Here’s my description: Sexual acts in public or semi-public places such as streets, classrooms, toilets, karaoke, parks, etc. And note: It's a tag for sex in public places that aren't meant for sexual activity. It's focused on the location itself, unlike tags like "exhibitionism" or "hidden sex", which are more about intent - either being seen or staying concealed. It's also different from "outdoor sex", which just refers to sex in open-air environments, that doesn't necessarily mean a public space, and most "public sex" scenarios aren't actually outdoors.
