Queefed in husbands mouth, is he justified in being upset?

My husband was going down on me and I accidentally queefed in his mouth he immediately got upset. I am embarrassed I apologized and trying to explain that I did not do it on purpose. Is he justified in being upset ? He constantly wants to stick his tongue in my butt and I am hesitant for this reason it’s embarrassing to me what if I queef or poop. I feel like he doesn’t understand vaginal health or how I feel and I don’t think he should be angry with me. Am I wrong for feeling this way?
