Help with Orgasms :/

Alright so I feel weird asking for advice but I’m starting to feel really crappy about myself. So little back story I’ve never orgasmed in my life and I’ve been sexually Active for 2 years now. I’m a very selfless, and self conscious person. But with that being said when my boyfriend and I are fooling around (mostly fingering) before sex or just for fun, I always start to get there but I always get really overwhelmed and even when I try my best to not move away or push him away I can’t help it. Today he told me he always tries to get me to orgasm and then I always push him away (which is true) I just don’t know what to do to fix that. Any help or advice would be nice. He didn’t mean to make me feel bad but I just kinda do because ya know I’m doing my best
