As for advice, set a time for blowjob only and experiment on him. Have him give you feedback, it’s important Give attention to everything from the tip to the balls with your hands and mouth If you want ideas let me know, I often asked different things when receiving a blowjob. Many times I was told “I’ve never done this before”
As others have said, find out whether there is a style that he likes. I like tongue only, no hands. Just gentle moves to let me feel the nubs on your tongue.
Put your ass in his face while you suck on it. That’ll help. It’s hard for me to come from a BJ also, and I don’t watch porn or anything. Pussy just feels better.
