If you can't get ass now, you probably won't get much more with more money or a better build. Suddenly being on the news with a winning half billion dollar powerball ticket or other sudden riches will certainly change this, but not much else will. Some guys have it, some just don't. Prostitution is big business.
I always got laid, even as a 140 pound toolish young college freshman douchebag with ILS, a Ford Escort, and no money. I just had to try harder than I do now, and the "women" were mostly immature girls my own age - with the occasional drunken, horny, over-the-hill, less than perfect, often chubby older broad thrown in.
As I got older, got smarter, more worldly and sophisticated, got a real job, became more physically and mentally mature, and became less of an all-around tool, it became easier to get laid - more and better quality / more mature women.
