This is a reaction to the short query by 'Anon', a 42 year old woman who is disgusted by her boyfriend's insistence on looking at porn on the web and masturbating. She mentions that the sites seemed to be about young teenage girls, and that she feels it is wrong for him to look at such material when in a loving relationship with her. She asks if he is normal, if there is any wey she can excite him, and if she should follow through on her current desire to leave him.
My answer is two-fold. First, I believe what the man is doing is normal and not perverted, so long as it is his fantasy life and he doesn't go seeking out other partners. I would also say that there is no reason to believe he cannot be sexually satisfied and pleased with her -- this may have no relation at all to whether he likes to check out nude pictures on the web. In other words, I don't think he is a pig or some other kind of disgusting creature.
The second part of my answer is that she should leave him, since the mismatch between her expectations and his expectations is so broad, this relationship is an accident waiting to happen. This is not an indictment of either party, but a recognition that they are unlikely to come to a 'meeting of the minds' regarding his behavior and her expectations. Let's be honest: if you already think of your boyfriend as a pig and perverted, are you really going to change your mind, no matter who suggests otherwise?
Good luck to both of you in finding the right match.
