Nothing I could recommend. All the sites I’ve ever come across are full of psychos and fakes. As the recent Ashley Maddison scandal exposed the huge majority of users of sites like that are men, but a lot of them are pretending to be women. You can’t even trust your eyes any more with the whole rise of ‘capping’ where guys use video loops of women to pretend they are real.
Even if they ARE real, they are either crazy, or just want your money.
So, Caveat Emptor… If you have to look somewhere then fetlife.com is probably the least bad but please take all I’ve said above into account.
