Boyfriend can’t make me orgasm

Hi! So I’ve had a boyfriend for two months and have had sex with a couple of other guys but no one has been able to make me orgasm apart from myself which I can do in about 10 mins. I get so close to orgasming, like it feels like I’ve reached the top of a slide and feels intense and good but somethings stopping me from going down. My boyfriend is quite upset about not being able to make me orgasm and I’m upset he feels as if it’s him. What can I do?
