Feminists play a role in this. What man wants a women who is constantly fighting him for dominance in a relationship? Especially men who do want a loving relationship? Nerds/Geeks want this monogamy relationship more so than other men, but are very... picky. Unlike men who move from relationships, who aren't very picky because they plan to move on anyway.
So is it a surprise that young men today tend to live a fantasy life, where they see nothing but porn and games? Feminism isn't the only reason for this, but it's definitely one of them. Either directly or indirectly.
Hey guys, don't you want a woman like this?
Or do you want to play Japanese games with Boob bouncing technology?
