Sex drive

My boyfriend is pretty chill and many times way too much, we usually have sex once a week 🥺. I need to do something to make him go crazy. Also he is very sweet and helps me with my homework’s and stuff, but I still feel like he does not care about me, like he doesn’t desire me or make me feel like “ the girl”. I have a great self esteem and I feel hot and whatever...but because he does not reinforce or comment I catch myself think about other guys, and desiring other guys, I know it’s awful and I never wanna cheat on him but idk what to do.
