WHEN I SAY "NO" TO HIM

im
I SAID "NO" TO GIVING HIM ORAL AND HE'S MAD AT ME FOR IT!?
Okay we we're talking about oral, i told him i would give him some tonight. He wanted some earlier than that before company came over. We hop in bed and he turns to my fav show. We lay there watching tv and I tell him "babe, I'ma be honest I really dont feel like giving you head rn, but I can later tonight." (He already had his pants off) He gets upset and turns the tv and says, "you know what? I dont want any tonight." 
LIKE WTF...... HE STOPS TOUCHING ME AND EVERYTHING.... like i still want sex, I JUST DONT WANNA SUCK YOUR DICK RN.?!
AM I WRONG FOR THIS?! I need to know........ ladies
