I cannot cum

Basically, I have no clit sensation. Fingering and penetration feels better for me, I really enjoy it and it feels great. I can have sex over and over, but no climax. I just enjoy it. I can feel my vag pulsating like I really love it but i just cannot get to that climax point at all where my heart races and it’s making me so upset. My bf has tried EVERYTHING. every direction..... everything. I’m getting extremely upset that i possibly can’t cum or have an orgasm. I think it’s impossible for me and it makes me so depressed. I really want to experience that. :(
