This site has been around for over 20 years and is one the longest running legitimate adult dating sites on the internet.
I'm not a member of any, purely out of curiosity - I was discussing these sort of sites with my housemates which offer casual encounters/nsa sex, like etc.
They said alot of the female profiles on there are fake designed to get you to pay up for full membership.
All I can say is genuinesingles is one of the best I've joined.
The site is easy to use and the members are real not made up profiles.
We cannot promise you will meet anyone but these are legitimate dating sites that give you the best shot at meeting women.
