I asked for feedback after sex

I left an abusive relationship about 3 years ago,it got to the point where i would only have sex with him to make him happy. I lost all the confidence i had at the start of the relationship. I didn't think I'd have sex again,well I met someone new. We had sex,when i asked how it was for him. He said "it doesn't feel like I'm sleeping with someone who's had 2 kids. It's as if you haven't sex alot". He was referring to my performance/movements as I was uncertain of what to do with myself at some points. I asked for guidance at some points (he wasn't referring to how tight i am).I get what he's saying. That was pretty much it in my last relationship. I feel like I've started all over again to be honest. At times i didnt know what to do with myself👀 how can i get back into the groove or things? At this point i don't even know if i can say we're not compatible or if he even wants to see me again at this point🤣
