I cant cum and it's making my boyfriend feel bad😔😔

I feel so sad and helpless right now guys😔 I think something is wrong w me😭 I understand that most girls cant cum from penetration alone... but I cant even cum whenever my boyfriend plays with me or eats me out😔 I can only make myself cum ONE way and I have to rub my clit super fast and tense my body up.. I think I've ruined myself😭

How can I get myself to cum from other ways therefore allowing my boyfriend to hopefully get me to finish? I've tried "practicing" other ways but I always end up having to go back to my one stupid way and I'm frustrated as crap and I feel terrible😔
