I do not care about boob size much. Even on a pure physical level a woman can be very sexy with small boobs. On a relationship level it is basically not a point. In my experience, women are more shallow than men. IMO men have more just hot sex encounters, but when it comes to girlfriend physical is less important. With the groups I hang out, the women usually have a hot guy. However I often see male friends with girls much less attractive than they are. I rarely see a hot girl with an ugly dude. Although I am probably wrong. Girls seem to have 0 interest in me, which would definatly add in some bias.
