Sex smells

My husband and I were having sex about an hour ago when he stopped us mid session and said that he smelled shit. We sniffed all around our bed and basically ended up on my ass crack which he said was the problem. (There was no shit anywhere when I wiped and this has never been a problem before.) I have always let him finish with me, even if I think he might smell like BO. I never say anything to him unless we aren’t having sex and he is itching his balls and I can smell it on his hands (which I’m not sure is normal but I have given him a lot of jock itch stuff over the years that he has never used). Basically I have never stopped a sexual encounter to tell him that he stinks. My feelings are really hurt. I found out two weeks ago I have cysts on my ovaries and I have been feeling down about myself since then....my husband knows this and still decided to tell me I smelled like shit While we were having sex tonight. Am I overreacting and being sensitive about his actions tonight?
