In the past 4-5 years, I tried (and I am still using) a lot of hookup apps and even more hookup sites to arrange hook-ups.
Also, I am using a few classifieds services, mostly it was CL, but when they close their personals section one year ago, I started with some local classifieds to experiment.
Any case, I tried almost everything but not I am on 4 hookup sites and 2 apps (Tinder and Pure). For me a bit better are sites than apps, I am having an impression that is a bit lower competition on sites. On the other side, I have the impression that 9/10 and 10/10 guys, bang all girls on apps.
