Again that's just porn. Every facet is targeted to maximise some goal. The girls involved are cheerleaders rather than volleyball players. By that I mean 5 foot nothing or less and easier to throw than a bouncy ball. The guys are at least 6 foot if not more, and relative proportions does all the rest before even skewing hiring of only guys who are above average size elsewhere.

When the women involved are that small/petite it doesnt matter if the guy is 6' or 8' or more, youre going to be talking sizes matching the woman's forearm if not longer. Throw in camera trickery for further illusions and you can very easily make it look like every guy in porn is hung, and even then most will be to some extent because only those who are will be hired.

Men see this and think everyone must be like that. Women see this and think that's what they should be getting. Difference is women are the ones on the receiving end and will find out very quickly if they do try and land someone endowed in such a way just how infrequently sex will happen because they aren't built for frequent use with anatomy like that.

But them they're also retarded enough to still think that's how it should be and will suffer because of social perceptions and idiocy.
