Is my g-spot broken??

Hello all...I have never actually orgasmed during sex. I do when I bring along a vibrator, but normal stimulation just doesn’t do it for me, and I feel so embarrassed when a partner says “are you going to cum for me?” “Did I get you to orgasm?” Like no dude. But I have no idea how to actually make that happen without my own external stimulation. Is my g-spot broken?
