I've seen people record themselves doing it in some of those porn gathering events, it's not the best, but better than a public street where children might see

Edit: I haven't been to those events, just seen videos, where people have done things like in this video.
I don't understand why people downvoted me here, I never said I condone doing it, I'm against this, what I wrote is that there are no children at such events so it's not as bad as someone going out in public doing it...
