A third of UK men seem to prefer smaller boobs
According to a research, 9% of UK men find large breasts to be a turn-off, while about 20% states they wouldn't even consider going out with women whose breast size was above a "D". Even more interesting is that 27% of respondents preferred the boyish figure of an actress like Keira Knightley as opposed to a woman with artificial enhancements like Pamela Anderson.
It seems Scandinavians, and other Norther Europeans, prefer bigger boobs though, according to an article on The Sun. The research also concluded that it seems women and men have different ideas about what attracts men to women. Seems surgical implants for the sake of bigger is not at all the right way to go. After all, having surgery simply for the sake of arguably being more attractive is not very impressive to most people, whatever their sex.
I would like to point out that it seems the core of the story is bigger boobs on account of surgical implants, not natural bigger boobs. Luckily, there's more to attraction then just looks. Women are attractive to men for many different reasons, and being voluptuous certainly doesn't damage a woman's attractiveness.
