I know it's general but sometimes there are general rules...
Most Helpful Guy
Considering I can't speak for all men, I'll speak for myself and say no. I don't. I care a little, but not very much. I can notice a pretty girl, I can talk to a pretty girl, I can find a pretty girl attractive, but I don't necessarily LIKE the pretty girl. I might not even necessarily be sexually attracted to the pretty girl.
Why won't I necessarily like her? Well she might just simply be pretty. She could be a totally awful person. There might not be anything wrong with her as a person, but I might have absolutely nothing in common with her. I might have nothing to say to her, or any chemistry. There could just easily be nothing there.
Why won't I necessarily be attracted to her? Well, it's not that I'm gay or anything. It's just that to me, sexuality is not entirely about appearance. Sure, appearance can help a lot. This is true. However, I can think of beautiful girls who do nothing for me, and girls who, if asked, I would say are not particularly attractive, yet have tons of sex appeal. It's more about attitude and personality than appearance. Same goes for being cute, too.
Those, right there were two prime examples of how looks aren't everything.
In my years, I've known a lot of girls, and I've dated, or had sex with a lot, as well. All shapes, and sizes, different races, and a few different religions. I don't really discriminate. It's all about who they were, who I thought they were as people, and what we shared, how we got along, what we had in common, and all sorts of other things. But whatever it was, in the end, had very little to do with looks.
To speak for other men, such as my friends, I have seen them with a number of different girls. Some of my friends were admittedly a little shallow when it came to their taste in women. Some less so. Some were with a variety of different girls. So I can say some of my friends are at least better than that. They're not all about looks. Not all of them.
I can also draw from another example. My girlfriend has this friend of hers. She's... she's not exactly pretty. I'm not sure I'd call her ugly, but I would say she's overweight, and other things about her are kinda plain. She has "manhands". Personality-wise, I don't really get along with her, much (We're very different people) but to speak to her qualities, I can say she has loads of personality, she can be fun, she's really outgoing, and she's kinda funny.
You might be wondering "what was the point of that last paragraph?" and I'm getting to that. The point is that she is never single for more than a couple weeks. Seriously, she has guys hanging off of her. She's been engaged at least twice, if not three times in the last five years. If guys only cared about looks, would she have so much incredible luck with men? Probably not!
So, thus in conclusion, I put to you this:
No. Guys do not only care about looks.3
