The breast envy

As a male individual of our species, admittedly, I was attracted to the curvaceous breasts of the opposite sex. But I have also noticed that this "breast envy" is not limited to males. As a amateur body builder, I have a sculpted body myself. My well-build chest is quite obvious even underneath loose sweaters. As a result, I have noticed the frequent staring at my chest from both males and females. Well, this made me think that the attraction of males to the female breast is not entirely due to gender differences.
