According to this comedian balls are gross, and from a woman's point of view maybe she has a point.
After all, other than making a man happy, balls don't really do anything for a woman other than being humorously entertaining as they bounce about.
Women don't complain about balls being too small or too big. Truth is guys to care more about about the size of the dangling bits, though women do tend to laugh at them if they are on the saggy side.
