Meet other adult members in your area looking for sex. "is a relationship site for people who want a fling, casual dating, or sexual encounter with men, women, transsexuals and/or couples.

My first recommendation would be to try Lavalife's Intimate Encounters section; you sign up with them and then decide which of the three sections you want to be a part of (Dating, Relationships or Intimate Encounters).
does have it's own sign in page however, as well as a different format, look and feel.
Fling has a number of interesting features that a lot of other casual dating sites forgo, including video chat, a blackbook feature (essentially a friends list), the ability to "safely" search (meaning: shut off viewing of explicit photos and video feeds),and put your profile in discreet mode (only allowing people in your blackbook to view your profile).
Every users home page also shows a random list of live cam feeds from different users - which although it makes the page load a bit slower than normal, is still a fun, frivolous, and very frequently used feature.
There are currently no membership costs for Fling.com, although their homepage states this is a "introductory trial offer for a limited time".
Based on the larger number of users and the membership levels of Silver and Gold, I had to wonder if is sharing the same user database as Adult Friend Finder, which uses the same terminology.
