C-Date is an agency that aims to bring people together for one simple goal: spontaneous casual sex.
Right now, there are already over 3,200,000 members in the UK who have registered.
Much like a social networking site, you can follow interesting members and read their posts.
The Casual Lounge has just stormed into the UK and already has around 100,000 members looking for casual dates, one night stands and relaxed affairs.
Cons: The US headquarters is not particularly good at removing pornographic images and weeding out listings of prostitutes.
