Is it weird

Is it weird he wont give me head anymore? Im embarrassed to ask why and honestly he isnt the type to say how he feels about things. He would probably just say "i dont know" and not say much else about it. He used to do it all the time but now that im pregnant he doesnt and he stopped right before i started showing. Im not sure if thats why. I heard you taste different while pregnant too but i asked him that months ago and he laughed and said no. So. Idk. Lol hes so good at it. I think I've only gotten it once in the last 5ish months. Im worried that I'm gross to him or something.
