I agree with deadhead. It's true that guys are very visual and sometimes we just need some visual stimulation. However, if you have a beautiful girl, whom you are in love with, by your side then you should not need to look elsewhere. I can understand looking if your girlfriend is not around, but clearly your boyfriend is not being sensitive to your feelings and you need to talk to him about it. If a girl asked me to stop looking through magazines I would probably try to defend myself at first as well, but would always respect her needs. I have to say however, that it is usually true that our infatuation with magazines and porn is not related to our relationships. It is almost always seperate and does not mean that we are missing anything from our actual sexual relationships.
