I have been using Blue Motel for several years now, I've had great sex and have also made some long-term friends. It may not be the cheapest sex dating site but it's not clogged up with false profiles like many of the large international/corporate adult dating sites.
Relatively Small, Real People, Non-Corporate, Value for Money. A lot of sexy women. Functionality is good.
Smaller member database than some of the larger corporate sites.
Steve Will does recommend Blue Motel to friends/family
