Others have said, but institutionalized settings can be good for getting the "vetting" out of the way. Why do so many romances originate in school? Because each and every participant recognizes everyone else is in the exact same position he is -- a subject of circumstance.

Streets, transportation -- these are low-filter interstices. Maximum wariness is warranted, really regardless of sex.

If you're not interested in going to the club, bar, art class -- what are you interested in? Seriously. It's tough. If your hobbies are sticking your head in the sand / introspective study (mine are), you will need to jump outside your comfort zone or else expect some degree of social resignation.
