porn is, as a rule, made by men and for men.
penis size in porn reflect the male fantasy.
for women, it's a matter of personal taste.
you're wrong as shit. most of the girls on brazzers and bb, rk have a big say in who they 'perform' with.
and I love porn, but hate how brazzers has "MILFS/Girls/teens like it big" on nearly every site name. if anything it makes the masturbators feel more insecure.
