I’m not interested in dating?

I came to the realization that I’m not really interested in dating right now. I’m 20 and I have sex pretty regularly but once that “need” is taken care of, I have no interest in dating. I saw a girl I know on a date at the coffee shop I work at and she just seemed to be trying so hard and it just looked very uncomfortable. Maybe I’m the weird one because all of my relationship experience has basically been me becoming close friends with a guy and then having sex with him. I feel like a slut but I feel like it’s not in my personality to date the way other girls do. I don’t want to act dumber or different. It just seems like so much effort haha. Does anyone else experience this?
