Are we speaking in relation to gravitational pull? If so, then yes. If not then it depends on the person and the culture which they are from to dictate prefference.
Americans don't seem to like larger girls because they see them as less feminine.
I do not really see why being very thin would be attractive, but I chalk it up to a fad. Curves are very nice to me. Obesity can be off putting but a nice looking girl who is lets say 5'5 and 150lbs is nothing to stick your nose up at.
I think that people expecting women to be very thin is silly. Women are supposed to have a decent amount of body fat, it's genetically imposed. So, if you do have some curves don't worry about it. Just keep healthy and fit, and like yourself. People who buy into the trend that you have to be stick thin are gullible morons who are less than original anyway.
Some, but most guys like medium sized girls and model like skinny.
I like how bigger girls aren't afraid to eat in front of you
If you watch Manswers (a tv show on the Spike network), one of things you will learn is that science has scientifically proven that men who are hungry will the attracted to "bigger girls". Why you ask? Because from an evolutionary standpoint, your brain is telling you that they have the resources your body desires.
Which they will tell you is "why you may not want to go to a bar hungry, because you might bring home a bigger girl" or something like that.
Absolutely! Of Course Their Attractive. Durr...
It depends on the person, but usually girls are less attractive.
Girls
Yes, a lot of girls find Omarion attractive, but other girls disagree with that opinion.
girls find guys attractive because it is someone to hold and cuddle gives girls what they want. :)
well your probably not attractive, and girls thing you have a small dick.
They're embarrassed because if they know other girls have bigger boobs than them, they feel like the girls that have bigger boobs are better and more attractive than them. If that's not the case, then maybe they think their boobs are too big. I don't know... You shouldn't be embarrassed about how big your boobs are. 
Not to be harsh, but fat to guys is extremly unatractive... And are a BIG turn off, so they go to skinny girls, because skinny is attractive.
attractive girls
No
If your 12 they are
This is not attractive at ALL to most girls. It makes you look feminine or girlie.
It means Big Beautiful Woman. It is used when women are on the bigger side, but are still very attractive. Don't hate on the big girls, they need love too!
