A 2005 study of data collected by the Pew Internet & American Life Project found that individuals are more likely to use an online dating service if they use the Internet for a greater number of tasks, and less likely to use such a service if they are trusting of others.
It is possible that the mode of online dating resonates with some participants' conceptual orientation towards the process of finding a romantic partner.
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).
My preferences would be Club Intimate, Fling, Adult Match Doctor, and Get It On, As for adult dating sites that I don't recommend, see my reviews for Shag Pal and Adult Friend Finder.
Stephen asks: "I am trying to find a 'real' adult dating site. The people on there either do not exist or are trumped up.
It seems all that I have come across do not have real/true information... I sent the company an email to complain, but they didn't reply.
Are you looking for an adult dating site that caters to adult encounters or casual sex, that isn't full of scammers or fake profiles?
If that's the case, I'll admit it's pretty hard to find.
