What kinda dating apps "hook ups" are mostly about?

I am coming out of a relationship and I am not really looking for anything serious right away. I am looking for some space to recharge and learn who I am now that I am a single man again. I am not really a bar/club type of guy and I am actually not very good with people. I dont have many friends at all. But I still miss having intimate connections. I've had tinder for a while now and match with girls but then I dont know what to do. I have had a bunch of weird interactions with people on there and I am a bit afraid of dating. I dont know if me being friends with them would be good enough.<br> I tried some other place like OkCupid and then I clicked on a girls profile by mistake and she messaged me, we got kinda along pretty well but then she said she was looking for a relationship. It was a really sad experience for me. I am starting to think that maybe I need to be in a relationship again. Its been a week since I became single and I am feeling a bit lonely.
