If I had a boyfriend I wouldn’t mind him looking at porn and shaking the dong to it, I wouldn’t mind. Nor would I mind if he watched the women with big asses and tits. But if some guy’s girlfriend feels bad about herself because her boyfriend watches that kind of porn and jerks off to it they perhaps should consider taking distance from each other if talking about it and make some sort of agreement don’t work. I know I wouldn’t want to be in a relationship where I feel physically and mentally bad about myself because my boyfriend can’t change or I can’t accept his choices or something in between.
Edit: I referred to a previous ask in this answer but it has seemed to be an error and the answer has disappeared.
