Being Satisfied.

My boyfriend is smaller in size and doesn't last very long. So I usually have to finish by him fingering me. It's never been an issue until last night. He was very upset and said he wasn't enough for me, because I can never achieve an orgasm while he is inside me. I feel terrible that he feels that why, but he won't listen to me when I say that he is enough. I just don't know what else I can say, any advice?
