Need advice

Everytime me and my husband have sex I can't look him in the eyes as we're doing it. I want 2 and every time I try I start feeling self conscious and I have 2 look away. I told him it's a problem I have and it's not because I don't like the way he looks. I just feel like he will make fun of my facial expressions during sex lol. I really wanna look him in the eyes and I appreciate any advice y'all can give me.
