Please help with oral sex!?

Okey so my boyfriend the other day for the first time gave me oral sex. He said it would be something unforgettable and im a little dissapointed about it because its supposed to feel amazing but he justt didnt make me feel amazing he even bited my vagina and it hurts! so should I tell him? like what are some tips when I see him and tell him that he didnt do great at all and that bitting should never be done to a girl! so please help! I want to tell him it wasnt great at all, and also can I get hiv from him giving ME oral sex? thankss
