Borf- if you're near a major metro area, check out
www.craigslist.org ... they have a page for a lot of metros, and there's a "casual encounters" section where folks try to hook up with other folks, using anonymous e-mail and whatnot.
It might help you out. I've never used it, so I can't vouch, I've just read some of the ads for amusement. Pity me!
