Wait has the Y gene dissappeared?.
But no real men have not dissapeared, that's like saying real women have dissapeared. Both genders run the full gauntlet of types. Maybe Men of today are different than they where a generation(s) ago but society changes over time.
In terms of relationships some prefer someone who is more masculine, some prefer someone who is more feminie. But as with anything both genders can display either trait or in between depending on the context.
