My boyfriends sexual inexperience ruins the mood. How do I resolve this?

When we first started dating over a year ago I was his first girlfriend and never been with a girl. I wasn't bothered by it and I was excited to teach him a lot about women and sex. I taught him everything I liked and how to get me in the mood etc. I have had to keep repeating myself for almost a year.

I am getting frustrated because he cannot learn what I like in bed and what gets me in the mood for over a year now. He keeps asking me every single time we do it, and often nowdays I have to just fantasie a scenario in my head to put myself in the mood because he cannot. My assumption is he is either lazy, he likes being taught or he genuinely doesn't care.

We have had arguments surrounding the amount of times we have sex, I've tried bringing this up and he says it is a hassle and women are complicated. I said I've taught him but he seems bothered.

Im genuinely fed up. I want someone who will go the extra mile like I do but I dont want to give up on him yet.
