orgasms

I don’t know what to do. I’ve been with my boyfriend for a long time, and he makes me feel so great, but for some reason, I can never orgasm. He does exactly what I like and what I tell him to do, and when I do that stuff to myself, I can orgasm just fine. What he does feels amazing, and it leaves me squirming all over the place, it’s just not an orgasm. I don’t know what else to do, and I don’t want to tell him I haven’t orgasmed because I don’t want him to feel like he’s doing something wrong. Is something wrong with me? Help
