>so basically it would happen in a body swap, possession, or complete genetic reset, but if it's just a basic transformation from male to female, it'd just smell gross and/or not register for them
I would say that's mostly accurate, though with the caveat that women's sense of smell is better than men's and sniffing used workout clothes would still be a turn-off. The most obvious route to go if you wanted to work the concept into a story would be a couple swap where it's pointedly established beforehand that the girlfriend likes the way her boyfriend usually smells, then when he's in her body he gets a whiff of his own lightly worn dress shirt.
