I'm guessing this girl is barely legal. But she's cute and has other "attributes" that attract men like flies. I'm willing to bet that she can get whatever she wants from men. Need a car, no problem. Need a nice house, no problem. Spending money, just say the word. I bet that ability to get whatever from guys started at 15 if she had any kind of sense to know this ...which she probably didn't and explains why she's on the internet LOL.
But in general, why are men like this. Why do you think a pretty face can make a man lose rational thought?
