girls/women have a sexual prime from about age 16 to 25. after that it goes downhill quickly.
men have a sexual prime from about 18 to 25. after that it is a sloooow decline. men get a good 15-20 years of sexual maturation where they have a much wider pool of sexual selection than their woman peers have.
your example is telling. it's a snapshot in the marathon of life.
i respect the way you feel, but there are so many variables in this description that imo it's impossible to parse any truth out of this.
small sample size, first and foremost. how old are you? what is this based on?
it sounds like you're just blaming women... if that's the case, we'll just agree to disagree.
then become exceptional.
assuming you are 18-25. right now you don't "win" the game by chasing tail. i agree with much of what you are saying.
you win by creating a lifestyle that effortlessly attracts the women -- not girls -- you want.
that takes time, investment, and focus on self. you don't spread your seed, err, i mean resources, willy-nilly to a bunch of girls. that's exactly what their evolutionary prerogative is.
