If you, hypothetically, have multiple dudes with different sized dicks and they’re all able to make a woman cum, what is it that makes the bigger/above average size into the usual preference/desired size?

Pretty much, if an average size (or below) is able to make a woman cum, what’s the difference that makes larger the preference?

Ex: does a larger size have the potential to give a larger/more extreme orgasm?

This includes girth, too, obviously.

Also, if you don’t have a big one, how would you go about fixing these problems/differences (especially given the apparent desirability of girth)?
