Now it's clear to me you're not being sarcastic. It's not about morals, I'm all in for you to have access to as much porn as you want, as long it's legal. If that's healthy or not for your mind, that's an entirely different story.
I don't trust you concerned "we live in a society" types any further than I can throw yous.
