I was looking around YT for this answer myself a while ago. I pulled up some pretty racy videos. The ones that really stood out were of some whacky Russian chicks who were topless and sucking their own tits while 'scissoring' each other in panties. They have a full channel of this stuff, some including guys. Nobody was bottomless or anything, but pretty sexual. The part that got me was the self induced titty sucking. I thought that was a huge no-no. But these guys have their own channel and a ton of views. So I guess you gotta try it and find out and see for yourself. I don't think there is a definitive answer anywhere. All depends if somebody feels like flaggin you or not.
