Men looks and youth driven only ?

OK

It sounds to me like the relationship is severely damaged, if not broken, and you need to consider your options.

I'm still concerned that the only problem seems to be porn, and while I have no quarrel with anything you've said, I am concerned that this seems to be such a big - if not obsessive - issue in your life.

I urge you to put that to one side long enough to consider the relationship as a whole, looking at all aspects, before making the decision you need to make (and I suspect you've made already). This is important; you need to be sure you are doing the right things for the right reasons, else you are more likely to end up in a similar place all over again.

BTW, not all men use porn; some have zero interest in it. You need to find out what any prospective partner thinks before you make your position clear, else you invite deceit (they may be thinking "I can manage without" / "It's no big deal" while for you it's a Big Red Line). I'd guess that many men would feel "My porn is none of her business", and feel deceit was required 'to keep the peace' - that's a guess I can't back up with evidence, but it's something to think about.

I'd also suggest you don't get involved in what porn they can have; that's a license to control that no decent man would (honestly) go along with. Life will be 1000 times simpler if you just opt out of porn guys completely, rather than demand to vet their porn.
