Idk how to feel

My bf and I were talking on the phone last night and I decided to ask if I was bad at anything sexual wise. He said yes I was not that great at giving bjs he said it just doesn’t feel good. I made a comment about how he’s my first ever bf I’ve never done it before and he brought up how his baby mama gave good head and he was her first. Then later he brought up eating out and said sometime it taste salty and again brought up how when he’d eat his baby mamma it was just like water he didn’t really taste anything. Idk how I should go about that whole conversation because it made me uncomfortable and hurt me that he’d bring her up when talking about our sex life.
