Despite having very small breasts, I never had any lack of attention from boys/men. I did not have intimate relationship with anyone other than my husband, but I dated quite a few guys when I was young (I met my husband when I was 17 and he is much older than me), and even though my then boyfriends were young guys (when they are supposed to be fascinated by big breasts), this was never an issue for me.
I must admit, few times I would get teased in school about my flat chest, but even then I always had boys chasing me.
I'm sure there are many men who like big breasts, but there are plenty who like small breasts, long legs, red hair, blonde hair and so on. My husband couldn't care less about my breast size, all he wants is that my butt doesn't get big
He actually doesn't even know about my NBE stuff (he just knows that I like taking vitamins and supplements) and would probably think that I'm out of my mind if I told him. So, I do it only for myself.
When we talk about woman breasts, he says "big tits are fun to slap around, but I personally wouldn't want to be stuck with them for long term". No offence to large-breasted women.
