Alternative to AFF

Agreed, I've found Fabswingers to be good in the UK (and they have a US section of the site although can't vouch for the quality).

I've met about 10 couples and a few singles off there in the last 2.5 years. Which, for a single guy, is a pretty good ratio. As with all these free sites though - don't even bother responding to people who aren't photo verified. There ARE good people on there (and it's a very active community) but there's a hell of a lot of fakes/timewasters.

My best find for weeding these people out has been using a reverse image search like tineye.com. If an image looks too good to be true, just put it in there and find out if it's lifted from a porn site... Good luck.
 
i posted a lengthy thread on this in the relationships section. not much else out there. depends on a lot of factors. location, standards, etc. a lot of people recommended craigs list to me. i found though that there is a lot of spam and scams on there. a lot of gay guys will contact you there too. it's rough out there. if you want to find women to have sex with, i think the bars are the best place to go, alcohol is involved. i've hooked up with a lot of girls on OKcupid. Match.com is too vanilla, although i've fucked a lot of girls there too.it can be frustrating because they're all looking for relationships.
 
I have personal experience with AFF, OkCupid, Match, Craigslist and of course here, and none have ever produced anything. I'd say OkCupid is about as a good a shot as any, but don't expect a lot and don't expect messaging chicks randomly looking for sex (unless you find the rare one who might actually state they want that-it happens...rarely) to get you anywhere.
 
okcupid is free, but if you join you can do complex searches on women that might be more of a match, IE if you answer a bunch of profile questions about sex, it will pair you with other sexually open women, however, be warned, even THEY too want a relationship. The problem is, what you're trying to do is find women who want sex and you're trying to defy nature and DNA. Women want relationships, especially if they're online. They go online to avoid the bar scene. So i think you have better luck at bars. Granted, i've had a lot of success online, where girls come over and we hook up, but it's A LOT of work.

i think i am qualified to comment on this, because i've been trying this for years :)
