I have two perspectives to this. I once had several male Indian roommates and I honestly don’t remember them having a scent beyond “male”. I could pick up turmeric from one of them, but I think he used a turmeric toothpaste.

I’m white and afab (not on t at the time) and a decade after having those roomies, I had a half-Indian friend tell me I smell like her dad lol. I think curry odor might just stick to clothing, I make it a few times a week so I’m sure my whole house smells like curry to outsiders at this point
