What is the real reason men need trashy magazines?

Let me start by saying that I know this type of questions have been asked a million times, but I need some honest answers...... Am I crazy for feeling low when my husband looks at those trashy magazines? I am normally quite confident in my own skin, and I am not bad looking, and our "bedroom" life is quite active. I just don't understand why he feels the need to look at that stuff. I know those mags are just a fantasy, but I can't help to feel that he looks at them because I'm not them. I guarantee that I do more for him than a paper picture can. So what is it? Is it something men just do, or do they turn to that when they're not satisfied at home? How can I get over feeling this way? I would really appreciate some honest thought.
