Completely free adult dating sites
After Lavalife, I only know of a few others that are worth mentioning, although I've yet to find one that's truly ideal.
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.
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).
You can use different handles in each section under the same account too, so no one will be any wiser if you want to advertise for one thing in one place without ruining your chances for something more should it come up.
If you've not yet joined Alt Scene sign up now, its completely free to send unlimited messages and only takes a couple of minutes!
Don't be fooled by other dating sites who offer free sign up but want you to pay to communicate, we are one of the only truly 100% free alternative dating sites.
Of course, new sites will debut that may or may not be of merit.
It's pretty hard for any site these days (especially the big ones) to stop fake profiles and scammers from signing up, but I think I get what you're after.
There are a lot of adult dating sites that don't have a lot of users, or use sneaky marketing tactics like the bait and switch you're referring to.
All you have to do is complete your profile with a bit about you, upload a picture and complete your favorite music.
So if you're looking for a punk girlfriend maybe an emo boyfriend or a gothic partner Alt Scene is a great place to start.
