no real women can be a barbie and be alive. the dimensions are impossible and when you remove the brain, they always die.
now, do men like attractive women? of course. do women like to look at attractive men? of course! there are objective qualities of what men and women view as attractiveness. there are some subjective ones, say a real tall person may be less attracted to a really short person, especially if the woman is taller, that kind of thing. but overall there are universal objective qualities to beauty. everyone notices and everyone looks.
i have never heard a guy as long as i have lived say he wants a girl just like barbie. i have heard them wishing for certain women that were attractive to them.
they may not come out and say it, but many really do long for the Barbie... perhaps it has more to do with fantasy...
