Guys who are obsessed with breast, are seriously immature.
You don't have sex to wonder how big a girl's breasts are.
If a guy loves you, they shouldn't even care. But if your not looking for something that serious, just remember guys will only care if they can suck on them, or they can pleasure you. I don't mean to sound like a freak but that's the honest god truth. I'm young and I'm in a C, and I'm still uncomfortable with my size.
I rather have small breasts, then the girls that have huge breasts and that sag down.
and if you haven't noticed, in most pornography girls get breast implants. See, those are the people you don't want to be because you will feel so much better without getting breasts implants and just flaunt what you have.
