I feel like there's a deeper reason to be pissed about our guys gauking over another girl other than jealousy. Our society has set up a standard of beauty that's just ridiculous and unrealistic
The looking is automatic,
Pattern recognition picks up signals of "fertility" or whatever, and the movement happens before the conscious brain has even got the message, that's when you get the very embarrassed looking away again quickly.
Scott Adams, who draws the Dilbert cartoons had a good blog post about a year ago - discussing the idea that artists with photoshop can create images that hit all of the right places in a male brain, far harder than any living human ever could.
You ladies have evolved to detect committment, so you tend to be a bit less prone to the purely visual cues than males are.
Ouch! careful with that! If something he does bugs you, try to let him know as close to the time as possible. Reacting to stuff from the distant past, rather than what is in the present is a PTSD thing, but it is not the best way to achieve your desired ends. Remember - the photos or the eye candy in the mall, won't give him grief for something he did 3 months ago.so months later after i had a list built up i laid it on him thick made him feel like a real a-hole....
but it won't give him a hug either... although it might take a little while for him to work that part out.

I have a friend who's ex could find porn taped to the underside of a drawer within 40 minutes of him bringing it into the house. When they first met, she told him that she didn't get jealous...
