Ok, I'm 19, 5'11, fit, 175lbs. Nice and respectful, and i love eating and fingering girls. Definetly not a creep and decently good looking with a nice smile. I've been wanting to meet up with a girl for casual sex for a while and tried Craigslist and a bunch of apps, but no luck no matter how I word it or try. I get replies from women but they almost always flake out for no reason in the middle of talking to them.... So, I was wondering SF folks, where should I look for casual sex? Do girls meet with guys just for sex? Or do they need a date and then sex? I'm not super confident and never was a really social person so help on how to be better at finding girls would be nice. Like to have fun with, but not get in a relationship with. I'm not super picky on looks as long as she isn't super overweight(i like curvy girls) or completely unattractive.
