Porn is associated with wanking, and wanking is stigmatised even though presumably most men have been wanking for far longer than most men have been using porn.
Porn is also associated with prostitution, which is stigmatised as well. And some men feel that although of course there is nothing wrong with the porn they watch, the porn some other men watch leads the featured actresses into prostitution.
And some men watch porn even though they feel it's morally wrong (and morally wrong things are stigmatised). They just don't have the self-control to stop themselves. (That makes them hypocrites, but most people are hypocrites one way or another.)
I get that "protect the children" is an overused slogan these days, and not just in relation to adult porn. But it's far from the whole story.
(n.b. I'm trying not to argue about what should be, I'm trying to talk about what is.)
