I’m bad at sex help

Okay so my boyfriend adores me but when it comes to our sex life I feel like I’m terrible there . About a week ago I took his virginity and we were a few minutes into it when I all of a sudden got dry.. so I stopped and he never nutted .. so technically he’s still a virgin ... then today I was giving him a hand job and 15-30 minutes went by and he didn’t even reach the pre cum stage ... he always says it’ll take awhile because he don’t jack off a lot but I think he says it to make me not feel discouraged... then I tried to suck his tip a little but he made a face but he kept saying it felt good and he said when I the tip it was good then but I just feel like he’s lying so he won’t hurt my feelings. What should I do ? Practice ? Take a break from sex ? Or ... ? I’ve tried to talk to him about it but he’s firm when he says it was amazing or good
