That’s fine if you both agree to those boundaries. Not every woman is okay with porn and that’s fine too.
I would never post nudes of myself but if I worked out and had a body I wanted to show off I certainly would post pictures in bikinis or clothes that I find flattering and would expect my partner to be okay with it.
Personally, I’m not a fan of porn but as long as it isn’t extreme or excessive I would allow it. I draw the line at paying for porn and interacting and also subscribing to an OF of someone he knows personally/IRL. I wouldn’t allow nudes or porn videos of any exes either.
Everyone has different boundaries and they need to be established beforehand.
