Dick size is connected to male ego. It can help you feel like a 'Man' or it can break your confidence.

I have a hypothesis that given two equally good looking guy a woman goes back to the guy who rough fucks her with bigum dickum.

"Shit! Dude how do you even compete with guys who're packing 8-9-10 inches?", thinks a lot of young men.

Women are submissive to big dick men and for women it's hard to respect men with not so big dick. We’re doomed.
