I'm 26 and have had a pretty solid dating life, but I've never dated an American white woman.
It takes a lot of time to meet good women, though. You have to be extroverted and make a lot of friends, who will introduce you to their friends. Don't expect results for at least a year. Even in Manhattan, I know some beautiful 22+ women who've never had a one-night stand.
Also, some advice: take a 3-to-6-month hard-line break from dating. You need to purge yourself of the misogyny that combat dating creates. I took a total break after I found myself, to my horror, behaving like an asshole to perfectly nice women. After that shock, I stopped dating entirely for 3 months, and met my current girlfriend after that.
