HOOKUP CONFUSION AFTER LONG RELATIONSHIP

Soooo I hooked up with a guy I work with.. we went out on a date, came back to my place and started doing stuff. I’m the type of girl that likes to give head but he wouldn’t let me. I tried to go down on him twice and he would pull my chin back up. So I was left a little confused, I’m not sure if he just didn’t want head or if I was doing to much for our first time? Or maybe I’m just over thinking it
