"Girls are like poop; the older they get, the easier they are to pick up."
As a function of time, your sex drive will decline sharply, but probably not as sharply as her looks will decline. (translation: both your demand for her, and the value she has to offer; are sharply diminished.)
As a function of time, her desire to get married, start a family, and feel secure & stable will increase dramatically. Your income and wealth will also increase sharply. (translation: your demand and the value you have to offer will sharply increase.)
So you'll be looking at these same women you're looking at right now and thinking, "I'd love to bang her, but it's too much work," and instead you'll be thinking, "I wouldn't take her even if she offered herself to me for free."
Men simply have more time. Women might say no to this guy, no to that guy, but if they're 25 and single; they'll start regretting every "no" they said; because now there are new 18-24 year-old girls in the dating market; and there's really no competition.
Men just have to wait. Are you complaining life dealt you the "wait" card? Would you rather life deal you the "rush" card? All you have to do is take your time.
It pays off. If you have a mom or grandma fetish, 25 - 50 year-old women will be more than happy to be getting the attention of a well-qualified bachelor. If you don't, the younger guys can't compete with you over girls 18 - 24.
You have a car, you have your own place, you have a career (as opposed to a job), and you're somebody in this world. When she introduces her "boyfriend", now she'll be saying "look at who I might get to marry me; and imagine the kind of lifestyle I'll have" as opposed to "look at who I'm f***ing; isn't he so cute?"
Lastly, a girl who is dating a doctor, feels more important and better about herself relative to other women; as opposed to a girl dating a personal trainer, or a construction worker, or a watch salesman.
You can always make the argument that, "what if that doctor is a bad person?" Well, "what if that loser is a bad person?" Why stop there? What if he's a gay serial raping pedofile? At the end of the day, ceribus pluribus (all else constant); the more financially powerful guy trumps the less financially powerful guy.
There are way more books targeting women about "how to marry rich, how to marry a millionaire, smart women finish rich, etc." than there are on "how to marry a nice guy, who loves you, and cares about you, etc."
So the same way you can walk into a strip-club and have a stripper dance for you or perform acrobatics at the drop of a $1 bill, is the same way it will seem like when you get a little bit older and more established.
The only trick is to not actually make the girl feel like a stripper or prostitute; try and hold your loling inside. Otherwise she'll feel bad and the whole "I'm a lady, I have respect for myself" will come out of her mouth; and she won't do it.
