Neither!! I like the 'Nerdy' and 'Quirky' SUPER-SMART girls, because they are a lot more fun to talk to!! I understand them, and I actually think they are REALLY hot, in their own, special way!! Glasses, DEFINITELY, make-up, no, clothes: whatever she likes...
That said, Barbie types can be visually eye-catching in a kind of "cheap" way. It's like how junk food might attract me, since a messy greasy french fries or something. But that doesn't compare to a beautifully-balanced nutritious meal.
I found in the bedroom, natural beauty is so much more appealing. Barbie types tend to be considerably less attractive when they take off their make-up and are laying there naked, and if they have breast augmentations, they might look very eye-catching in a dress but her boobs feel awful when you're actually on top of her.
Those barbie girls are like empty shells, no activity going on inside where its really needed. If you haven't got it inside it doesn't matter what you do to the outside. Give me the girl next door type any day of the week. Id rather have a cute, smart, funny girl than an ice cold glamour girl who thinks the whole worlds watching her. Fuck that
I personally think that being natural and glamming it up like a barbie on occasion for appropriate places are okay. Unless I'm going to a party or clubbing (I've never been to one but you know what I mean) I prefer a natural but still with some type of makeup on for everyday use. Nothing too crazy that's unnecessary.
