It's probably because, if you are the type to go so out of your way to look like a "porn star", you are probably pretty "easy" too. So if you spend hours and tons of money bleaching your roots, buying push up bras that give your breasts gravity defying power and going in the microwave, you might as well get rewarded with some shallow guys testosterone for wasting all the damn time trying to look so ridiculous.
So in a way, it's because those shallow boys are attracted those shallow minded girls because the boys know that the girls go out of there way to look like that for the boys that are willing to stare all day.
More chances on getting "some"? Or maybe orange balloons are a turn on? It's a mystery isn't it?
I'm sorry, that doesn't really answer the question, does it?
Well, in any case. I don't find that attractive, to say the least. I like fair skin, I like dark hair, I like real boobs. lol.
