Fictionally, for example in yiff. It is a hell yes for me. I like to imagine a reality where sexuality is something more normal and can be lived openly.

In reality I say no, especially in actual public places, where a lot of people are. Since obviously the viewers do not consent to that.

Recently I heard that there are events or similar that allow this. Which sounds cool.

And a grey-zone is, doing it at hidden places. There it seams to be a risk/reward thing ;).
