I agreed with Thundarr. Perference is fine. I prefer a woman with a larger breast size (not mega-huge or anything, but more than a handful on each side
) . Now, if I was single and started dating a wonderful lady, someone who had a great personality, shared many of the same ideals as me regarding children, life, finances, etc. and someone I thought was marriage material, I wouldn't suddenly toss that out if I found out her breasts weren't quite as big as I would like.
Would it be a bit of a disappointment? Sure, but there is so many other qualities that make up for it, that there's no way I'd toss aside a great women just because she doesn't wear a D-cup, something that was decided for her before she was even born and she had no control over (outside of surgery).
If someone honestly said they'd toss aside a wonderful man because he was circumcised/uncircumcised, then to me, they are pretty damn shallow. I mean I can understand there is limits to physical attraction, such as if the man/woman is morbidly obese or something, but over the size of her boobs or over whether or not his penis has some extra skin on it? That's weak sauce to me.
