Distant (bad sex)

I met this guy, Online, We actually went to high school together, but didn't really talk. He messaged me on Facebook, and we sort of hit it off, although we don't really talk throughout the day, We somewhat do talk. We agreed that we were going to vibe with each other, and see what happens. We met up this weekend, and of course had sex. I'm not going to say it was the best, only because I know we were both nervous, and well I was having women issues (tightness and bloatness) Anyway, He still texts me, But I don't know if I'm reading this whole vibe off, I feel like he's somewhat become distant or like he feels forced to message me? I don't know, maybe I'm reading into this re

ally hard. He still likes my pictures on Facebook.. What do you guys think? Should I send him a thank you for the bombass d*ck, to kinda boost him up?
