As a girl, and as one in a relationship for the last nearly 5 years. I think this is her hang up to get over.
I don't watch porn. Ok that's not entirely true, I have, but I don't very often at all. Not that I have a low sex drive, it just doesn't appeal to me. And in all honesty, I kinda agree that it's harmful towards women. Not as a universal truth, but there certainly are women in open who don't want to be because they're desperate. Like all sex work. But that's a separate discussion. As it stands it is what it is, taking away the option for desperate women to engage in sex work without anything to provide other help isn't certain to help anything either. Back on topic...
I don't watch pornography. My bf does though, and used to and occasionally still does try to hide it from me. I have no idea why. I've told him over and over that I'm not going to think he's a pervert for looking at porn. No, not kinky porn either. I'm sure id have a limit but it would have to be very very extreme before I think id have any problem with it.
Guys masterbate, they do it when they're single and in my experience they often do it in relationships too. And I don't care. I wanna be able to find other guys hot without feeling guilty. And I don't think hiding shit from each other brings anything but drama and possible breakup to a relationship.
She has a right to not wanna have sex as much as you do, and you have a right to fulfill your sexual desires elsewhere so long as you aren't cheating on her. (and no, you can't cheat with someone who has never heard of you or met you. You could argue that there are noncheating ways to betray the other, but it's not cheating in this case) If she thinks you're a pervert for what amounts to just being a guy, I dunno, she needs to figure out how to deal. Maybe she should consider joining the other team, lol. Seriously though, I dunno what her problem is. Being upset with you because she feels you don't want her I could understand. But thinking it's perverted? Seems really old fashioned. I may not like the pornography industry but that's entirely separate to people viewing it online.
Point is. I don't think you should have to hide it. Personally I'm more upset about my bf hiding that he masturbates from me than the fact that he does. It makes me feel like he doesn't trust me to understand, or that he thinks id judge him over nothing. It doesn't make me feel insecure. Maybe he doesn't feel like actually having sex right now. Maybe he thinks I don't. I dunno. But it's not near enough for me to think he secretly wants another woman, and it sure as hell doesn't make him a pervert. If I got jealous about shit like that, how can I expect him to be ok with the fact I have a lot of male friends and have since before meeting him. Many of them are single. I don't want him to be jealous. I want him to know he's the only guy I wanna share a bed with. I'm his girl, having guy friends, finding other guys hot sometimes, even occasionally fantasizing about other guys, none of it means shit. I'm his, and he's mine. I know a lot of relationships can't seem to function with that level of trust and absence of jealousy, but most relationships fail so I hardly see what most people do as something that is wise to imitate. He has a female friend, and they used to be together. And them hanging out doesn't bother me either.
When it comes to jealousy, it's all about trust. But this seems to be more then that, she seems to be prudish, and that's probably a lot worse. When jealousy is irrational you can often get the person to see it's irrational. But when someone's just a prude, they often feel no need to defend it based on reason. They expect people to accept it on the face of it.
I don't know what you should do. Try and find out why she thinks looking at pornography makes you a pervert. Does you wanting sex make you a pervert? Does her? Sounds like she was just brought up this way from having read the thread. In which case, I hate to say people should end their relationship, but perhaps you should consider your long term options. Your relationship doesn't look good ln term if you have to hide something from her indefinitely and if she won't change.
As for everyone talking about how porn is harmful to women. In all sorts of potential ways. I kinda agree with you, but come on, make a thread about the subject. Don't you think it's off topic here? I've told my bf I don't approve of the pornography industry, but made it very clear that I don't judge him for viewing it. He's not supporting its creation. I know he's a good man who would never hurt a woman. That shit is out there no matter what he or I do. And not EVERY woman is unhappy bring apart of it and doing it out of desperation. It's a complex situation without simple solutions. The important part for me is that I love him, I know he wouldn't hurt anyone. And while it may well be while he tries to hide it from me, I'd rather he be honest about it. Because I don't consider his viewing of it as making him responsible for every uglyness in the sex trade world.
Oh and...
Females want to have it both ways. You can't win.
Fuck you.
