annoying sex talk

So I don't know if it's because I'm PMSing or if I'm just finally getting to the point where what he says gets on my nerves. I told him to come into the bedroom because I wanted some, so he comes into the bedroom and starts playing stupid and changes the pitch of his voice and asks like "oh what are you doing?" "Oh you wanna have sex?" Like he doesn't know what to say, honestly he doesn't need to say anything at all. But it's been getting on my nerves because he does it EVERY TIME. we've been together almost 6 years and it makes me feel awkward and makes the whole situation awkward so it completely turns me off. Do I tell him or would it hurt his feelings?
