Boyfriend calls my orgasms “little”. Confused on if I’m orgasming right?

Essentially the title. 18f and he says it in a sweet way but I’m just worried I’m not really doing it right? I have a very sensitive clit (I can only play using the hood) so when I get too overstimulated and have what I thought was an orgasm it just gets too sensitive to touch in general. He keeps going until he’s done and I don’t tell him it’s painful. But am I doing something wrong to not get a full orgasm??
