Actually, before the sexual revolution, it was pretty straight forward. You only had sex once married. Simple, easy, unmistakable.
Then it was anything goes, and, yes, some of the presently uncovered perversions, are all part of that revolution and self discovery, as is now the realization that some sort of clear and simple lines need to drawn.
If what's going on now, this re-writing of previously understood rules and boundaries, is any indication of whats going to follow, it won't be clear and simple, and be anything but.
Imagine that you'll have to protect your future with a signed check list of what was understood to be permitted and what wasn't understood to be permitted.
Any wonder why some would be inclined to just say 'screw it' and get a sex robot?
Now, if all you can muster on a serious topic is "can't even heavy-pet 14-year-old girls when you're in your 30s", there is no need for you to respond further. (And where the hell did I bring that into the conversation? Yeah, that's on you)
