I ate my boyfriends ass? am I doing it right

Me and boyfriend are very sexually active and safe. We try everything and new things, however yesterday was so weird it started from him massaging my bum and slipping a finger up there for me doing the same back, but I kissed it as a joke and he liked it so I just started licking his bum hole and ass. He loved it. Sounds dirty I know but I did it and it wasn't to bad. I liked it I guess as he was pleased and it didn't taste bad. What are u supposed to do when eating ass? Like just lick around it or 😂 no judging please lol, I said I'd never do it untill I did yesterday
