oral sex hurts

my boyfriend and i are pretty sexually actively and he really enjoys eating me out, but it hurts. I genuinely feel like he’d be good at it but my clit is just so sensitive i’m in pain the entire time. I don’t want to hurt his ego but saying i’m not a fan and i’ve tried moving my hips so he’s not right on my clit but it doesn’t work. It feels like he’s trying to give me a hickey right there? does anyone else’s boyfriend’s do that or maybe mine just is bad at oral? help!
