Well I suppose I can only share my experience :) And what I heard from women who have shared their thoughts with me.

Women have definitely told me that in general, hung men don’t put in as much effort, certainly with tongue, but also emotionally. So it’s easier for Mr. Hung to be one-night-stand guy than relationship guy. I hear a lot of that in Burner/Hippie communities.

The other catch is there is such a thing as too big. I’m not massive, but I’ve definitely hit cervix before, wanted to go further, and been told it was getting painful. One gf, I think she became very close to choosing somebody else who was I’ll say a better fit. I felt about the same as if she were looking for a better fit the other way around.

Again, can only share my own experience.
