BF (M22), finds me (F22) too shy in bed

I have a little problem with my boyfriend We started to have sex a few months ago, he's not my first but even if he likes it, he still finds me very shy, i dont really what can i do. I wear sexy clothes, touch him kiss him But I don't think I touch him enough, I can't look at him during sex and during bj, I'm very shy, I feel some embarrassment sometimes. I don't really like my body

I want to get better,he wants to help me but I have severe anxiety issues, and to think that he might be frustrated is crushing my self esteem

I really need help, I want to surprise him a lot and work on this problem
