Siri, find my G spot.

WHYYYYYYYY is it so hard for me to orgasm? I can have a clitorial orgasm, easy peasy. But I've only come close to having a real one maybe once or twice when having sex. My boyfriend has gotten me REALLY close when fingering me, but he always stop right before I get there (not knowingly i assume) HELP!
I enjoy sex a lot! It annoys me when people say that you can't enjoy sex if you don't orgasm. BUT IT WOULD BE AMAZING... if I could...😂 any advice?!
