uptown: he's pointing out women who are PHSYICALLY beautiful. That isn't, or shouldn't, be the reason that he is with YOU. there's something special about you that says "she's worth spending time with. Worth talking to, and worth caring for." I'm having this argument somewhere else on the board right now... so here's the readers digest version: BEAUTY DOESN'T MATTER. that's it. who cares what you look like? If I can like and dislike people over the internet, and care about people I've never seen, then what do I care what they look like? And why should you care if you don't look like the dusky model your boyfriend points out as beautiful. he wouldn't be pointing them out if he didn't think you wanted to share that with him.
If him pointing out other women makes you feel second rate, maybe you need to discuss that with him? Maybe he doesn't realize how that makes you feel. Men aren't mind-readers, no matter HOW hard we think at them. if we dont' say "hey, you are making me feel like dirt, now stop it!" then they won't get it.
as for pics, my boyfriend is hte ultimate porn-filter. he wanders the titty board, and sends me the most choice spreads

we share them together. Neither of us look ANYTHING like the men and women in the pictures, but it doesn't matter. i love him because he's smart, funny, and a quick thinker, not because he's Fabio. :P and the same can be said of him, although he definitely makes it clear he appreciates my... hmm, physical attributes, as well.
