My bf just told me that I never talk or tell him what I like during sex and that's why he only asks for head.

How are you able to talk during sex or make noises ? I have never done it I feel like it would sound fake coming out . so that's why I don't feel comfortable doing it . It hurt my feelings that he told me that. I've told him I don't feel comfortable doing it and his response was that I'm probably fucking someone else and that's why I don't enjoy it.
