Does penis size ever actually cause sexual compatibility problems? I'm 15cm and I've experienced tight fits and "hot dog in a hallway" but generally my average dick seems to be fine for the average pussy.

Do guys who are like 4 inches really have a disadvantage in pleasuring the average woman?

I get that "higher consciousness" makes relationships more tolerable of "lizard brain" faults, but there's only so much tolerance if the dick cant satiate her desire to be "filled" by penis. But maybe that craving is met with two inches at the entrance. Don't know.

Posting in Bant becuase the question is relevant to international/interracial pairings.
