The longer I date, the less I know what the fuck I'm doing

I swear, I feel like as I get older dating keeps becoming more and more of a foreign language to me. I was dating or in a relationship pretty consistently throughout college and now two years out and I can't seem to connect with a guy longer than 2 dates.I don't think I'm any more socially awkward than any normal person, but I just feel like I'm not keeping up with something and I was never aware there was something to keep pace with. Does anyone feel this way growing older?
