I would say more women are directly turned-on visually by big balls than a big c*ck. Makes sense if you think about it. Never thought it might be like that Mojo.
If women like big balls, is there a male reversal of this where men like large labia? Just curious?
I look at things for male and female equivalents, bell curves, social influences, etc.
One TV program I watch said that sexual satisfaction is low for many women because too many men equate penis sensation and think vaginal sensations are similar.
Sue asks the male callers if they can have an "O" with just getting his testicles rubbed.
Back to large balls, more sperm so more babies? More power, More/better what? Small testies in a species indicates the male rules because of his muscular powers.
Anthropologist (Helen fisher) say males that have larger balls is a sigh females are more promiscuous. The males need more powerful equipment so their genetic contribution has a better chance of fertilizing the female's egg.
