Its more that you guys are stuck on objectification and titillation than aesthetic appreciation.
So long as they're only stroking their chins, it's not a problem?
Seriously, though, objectification can be misogynistic, but only when appreciation of someone's appearance is accompanied by a sense of contempt for their other relevant attributes. We all judge people on appearances, and, while that can pose all kinds of problems (which go far beyond questions of gender and sexuality), I don't see how wanting to look at features you find sexually attractive is anything to be ashamed of in itself, so long as you don't judge people on those terms - or focus on those features - when the context requires other considerations be treated as more important.
If, sitting in our lounge, my wife and I discuss how hot some model (of any gender) looks in a picture, every other consideration but those sexually-significant features is irrelevant, and I don't see that we can be accused of doing anything wrong. If, by contrast, my coworkers and I sit around in the staffroom rating our colleagues by those same features, we are definitely out of order. Even then, though, such objectification need not constitute misogyny, not least because I haven't specified the genders of either the raters or the rated, but also because it need not involve contempt for anything else about them.
Edit:
Nah, its more like unwanted TMI and that dude who puts his whack material on the wall of his cubicle at work.
Those might be evidence of misogyny, but, alternatively, they might be evidence of a difficulty recognising appropriate boundaries, and a lack of sensitivity for other people's feelings. Either way, it's not something that should be allowed to persist; we should be careful, though, not to ignore the fact that a lot of people have problems with boundaries and social sensitivity. Where we want to correct inappropriate behaviour, it's important to understand what's behind it, and throwing the 'misogyny' blanket over all such things does nothing to assist us in that.
