I think that you pegged it. The folks who I have known who were consumers of pornography (there are quite a few in our universities) are among the silliest folks I have known. They live in a perpetual state of junior high school mentality. A classmate in undergrad spent a lot of time and money on pornographic magazines and yet lamented that he did not have a girlfriend. I once asked him why he didn't take that time and money and put it into dating a real flesh and blood woman. he did not have an answer and the expression on his face indicated to me that he had never thought along those lines.
yeah exactly! I just don't get it. If a man is in a committed relationship with a woman, then he shouldn't need to look at other women.
