no sex????!

My boyfriend totally rejected sex tonight and I'm so upset because all week he's been asking for head but I didn't want to give him head because he would sweat and I like a clean smelling penis. lol today was supposed to be the night! Instead he got mad about something I said I front of his friends and totally rejected me in the bedroom after I apologized and tried to make up for it sucks! But now I don't wanna have sex with him either, rejection freaking hurts!! Should I be mad? Is not giving him some a good idea? Hmm idk
