Have you ever questioned if 20 years old females are as desirable as they think they are? Because they are not.
Pretty handy to make all the fault of "males" while never ask them what desires they have, what they want in the other person while constantly emphasize females' desires. Have we ever question women about their own standard? Are they too high? Are they what men want? Do they bring something on the table or it's the usual "I'm a passive princess: entertain me, jester!", because if it is I prefer porn, it usually doesn't ask to pay for a date.
