Don't ask questions when you don't want to hear the answer!
Honestly, I think you need to relax about this, you're trying to analyse something that isn't even there for most women. What would you say if a woman posted asking whether a guy would still like her because she had a flat chest?
You would tell her to snap out of it. Of course boys prefer women with giant chests purely because it's in their genes, in the same way that women prefer taller men because it's in THEIR genes to want to feel protected. It's not about being vile, it's about being human.
However, that's NOT to say that someone with a flat chest is unattractive any more than someone being short is unattractive. Of course we all have our preferences, but at the end of the day the part of the body (whatever that is) that makes us human, not animal will always dictate that a good personality etc. will override physical features.
That's why if a woman put on here one hundred threads asking whether her chest, or her weight, or her nose etc. affected how attractive she was, you would tell her to stop being paranoid. To an extent, there will be people that care, but by the same token there will be people, the worthy people, who see her how she deserves to be seen. No-one is perfect.
In all seriousness if you're wondering why you haven't got a girl it's got bladdy nothing to do with height. It's got everything to do with your obvious self-loathing; women don't want to get messed up with that. It's that simple.
