AITAH for stopping my husband from correcting a woman who called me "Sir" ?

To avoid confusion, we live in a part of the US that doesn't snow. I (31f) have a blonde pixie cut. On that day, I came from the gym. I was in sweats. No makeup, no jewelry. I met my husband (28m) in a crowded place.

While walking with my husband, a woman (possibly 30s) bumped into me. She said "Sorry Sir." My husband stopped walking and he was looking at this woman. He was about to walk in her direction but I held his hand. He told me he was going to correct her. I told him I'm fine.

As soon as he got home, my husband told me that I'm gorgeous woman who definitely don't look like a man. I said thank you. He said he wished I allowed him to correct that woman. I said it's okay. He told it wasn't okay what that woman said and it wasn't okay for me to stop him from correcting her. My husband kept going from assuring me to being angry I didn't let him correct that woman. Am I the asshole ?
