im into chicks (yay bisexuality :D) and honestly it varies for me. I think in general, I might focus more on body because I can just see beauty in a lot of peoples faces. face is ultimately my focus but I'm just not super picky about it. I like really nice big pretty eyes with long eye lashes though. lol I like eyes.
Being ridiculously gorgeous in the face is great but its not really important for me. However, if you're too skinny or too fat...that could be a prob for intimacy and me being sexually attracted to you. granted, I like chubby girls and bigger girls who can hold their weight well or are taller. there's definitely a line though. I'm pickier with guys though. I don't think I could go for a really chubby guy at first sight. I'm not so into skinny chicks at first sight. I like some but generally I like curves better. I mean some girls just look so pubescent to me but tons of guys will think they are hot so everyone sees things differently. If I see a very pretty super skinny girl I can appreciate her beauty but I might not have the same sexual attraction at first sight that I will more likely have with a curvy girl. It depends on the person though. Some skinny chicks are hot. Personality changes everything but you said at first sight so yeah.
And I don't sit around rating people so, no, but here's the most attractive to least attractive for me.
1. Average face with great body (for me that means really curvy). perfect.
2. Good looking face with an overweight but not obese body. Great.
3. Good looking face with an average body. Pretty good.
4. Below average but not ugly face with a great body (curvy curvy lol) It's cool boo. I'll do your makeup.
5. Good looking face with a super skinny body. Eh, not my style but maybe her personality's good.
this is kind of off considering everyones perception of beauty is different. whatever an "average" face is supposed to be can be vastly different across the board depending on whos looking. same with what a good looking face is. Same with "great body," "average body," and so on. I can't count the times I've heard one person say "damn she's hot" and their friend will say "eh. she's okay. not really my type." that's how the story goes kid.
I think this would be more effective if you narrowed it down specifically with pictures. to show people what you mean when you say great body, average face, etc.
in general, if a guy can see beauty in different types of faces by default, he might just focus more on body types. however if a guy is really picky about faces he won't care as much about body types. some guys don't have a standard and go with the flow. others are picky about both
