Help me

So my boyfriend can’t get me to orgasm when he fingers me. And I never lied to him about it cause I wanted him to get better. Idk what to do. Like it’s very pleasurable. But I just never climax. And I’ve noticed he’s gotten better actually but again I just can’t get there. And he feels terrible about it and is kinda obsessed now. Like is there something wrong with me cause I can sometimes struggle to orgasm myself when I masturbate?
