Not in "the mood"

Okay so today, I haven't been in the mood to have sex, and I was trying to be nice about it with my S/O but he kinda just threw a little fit.. Not really but kind of saying that I pretty much have put him in a bad mood for assuming that he was pissed off at me because I didn't want sex. (Make sense?) then he got up and went to the bathroom in a stormed off way.. I'm annoyed and a bit hurt that he dosent understand I suppose? I don't know but I just had to say something.
