Physically eating me?

One time when me and my boyfriend were having sex(oral) he BIT my Vagina. It hurt a bit, but I let it pass as I though he would only do it once. Nothing else happened as we finished, and we never talked about it again. Another time when we had sex(oral) again, he brought a FORK with him to the bedroom. I didn't know what he was doing with it, and didn't question it. Later on he grabbed the fork, and lightly stabbed my Vagina. It didn't feel bad, until he shoved it in more. He shoved it in so much I told him to stop, and he did. He apologized, and we switched to anal sex to finish the night off. Ever since that I've tried smaller sex toys to masturbate with, and they felt as good as the fork but with less pain.

Is this normal, and has anyone tried/done this before?
