AITA for asking bf to wash hands??

Recently was on meds to help treat UTI, think I had 1-2 days left of pills to take to be good again. We’re in the moment and before things go any further I stop and mention to my bf that while I’m down to have sex, I had a silly one time request if he could wash his hands just to be extra precaution until I’m in the clear. He immediately was turned off and started to question me, and then say “so you think I’m dirty?” I was now feeling awkward and ashamed and so I was now anxiously trying to explain to him without getting him more upset of how it’s just a one time thing and that no he isn’t dirty, or how we can just wait until the next day if me asking to wash his hands is a big deal. He gets up and starts walking toward his door and says without looking to me “no one has ever asked me to do this before, wash my hands before sex??” and just walked out. I sat there just feeling really bad and uncomfortable. He comes back a few minutes later acting like nothing happened and said “sorry to hear you have a UTI, that must be hard.” We proceeded to have sex, but can’t say I enjoyed it at all after what he said and made me feel like…🫠 Was I wrong to even have brought it up to him?? Like over sharing?? If roles were in reverse, I wouldn’t hesitate or question him because I’m being respectful of health concerns.
