Why do guys check out other chicks when it hurts their girl?

I was looking in some magazines and commercials today, and the majority of the ones I found were - cologne's/perfumes/body sprays; underwear; Shampoo's and shower products; beer/cigarettes; energy drinks/products and automobiles - and they all used sexuality, in an in-your-face type attitude of an advertisement. They used both men and women, but the majority was using women in the advertisement.

And my answer now might get a little hazy, but I'll try to pull through.

I stare around the classrooms and lunchrooms at school - the majority of people using their imagination are women - writing, drawing, doodling, taking notes, typing away, reading - you guys are always thinking.

Now I looked at what people were wearing -
Guys: baggy jeans/hoodie/t-shirt/khaki's/button up shirt/sweater/sweats. Something like that
Girls: Well, girls seem to be in more in tune with keeping up on fashion, so there's a long list to go on here.

So what I came up with is that a majority of women are better at using their imagination, so I think that they sort of have to use their imagination more when it comes to looking at the opposite sex, (like, even at the beach, look at the different bathing suits for guys and girls) and guys sort of probably day-dream more - leaving them to stare? Idk, I'm hypothesizing.

And then I was watching television, and I noticed a guy holding up his hands in a framing motion - focusing on a girl watching down the street in a crowd and he said "Now that's a ten! " Now, I never saw a girl act in this way, girls seem to be more subtle, more innocent in noticing things like that. Lol, my hypothesis?

A-R-Norman,

If we, men, were as refined and cultured as women then you'd feel sad because there would be no need for improving us. Heck, we'd be women just with different accessories and that would not be good.

The reason we tend to stare is because we are slow and it takes us a while to fully take in the full effect of the scenery. Women on the other hand had nature on their side which has enabled them to quickly analyze a picture, process it, and decide upon it hence they know within a matter of seconds whether the man is worthy or not. :)

I have to say, the only reason I did that in my previous relationship was because she was looking at girls and commenting on them. "Oh she has some badonka-donk", "Oh look at those boobies", and last but not least "I'd hit that". This made me feel that it would be OK if I commented too. But it wasn't and here I am, all alone at my computer helping you figure out what the problem is. Females are strange creatures. Make sure you don't give him the same false impressions I got by talking to him (e. G. How it makes you feel). But what do I know, I'm Just A Random Guy.

I think guys are hard-wired to notice attractive females. That having been said, there is no reason to be rude and disrespectful to the person you are with. Good manners should prevail, here!

I really like the way you find the real problem with "looking at other women". I totally agree. I've always checked people out but not been able to explain the difference in what I'm doing and what some guys do. Thanks for helping me explain it.

I agree. It's all about your partner's comfort. If my boyfriend or girlfriend wanted me to stop checking out other people, I'd do it for them. But I also think that if an attractive person walks by, it's going to be natural for me to look. And it's not going to bother me so much if my partner does the same. It's one human being appreciating the attractiveness of another human being. As long as s/he doesn't obsess over that person, of course!
