How to deal with objectification?

I've recently picked up electric guitar and have started taking lessons. My teacher is a man in his 50's who seemed sweet and supportive. However, at my last lesson we were talking about how I'd like to join a band since I can play bass as well and he said, "A hot chick bass player will be in high demand". I was so shocked by this comment that I brushed it off, but I'm intensely uncomfortable with how I was directly objectified to my face and I feel like I should have said something.

Does anyone have advice for what to do if a man says something misogynistic? What should I have said? I feel like the right thing to do is to either look for a different teacher or confront my current teacher about how that comment was inappropriate. I no longer feel safe being in a room with this man after he's revealed that he was thinking of me in that way.

UPDATE: I did tell him it was inappropriate and got an even weirder answer. Currently on the hunt for a new teacher. Thank you all for the wise words 💖
