Orgasm from Sex?????

So like when my boyfriend and i have sex i don’t feel anything... at all... nada. And he always asks me like “anything?” “nothing? seriously” and i’m like noooo nope sowwy. but like when he gets his fingers on that clit tho it’s a whole different story and i feel GOOD. but like, why don’t i feel anything when he’s inside of me? i’ve always heard sex is just the most amazing thing ever but it just isn’t for me? what’s the deal?
