Wondering if this is an unpopular opinion: if you don't like the unwashed smell of your partner then that's your body telling you you're not a good biological match.
I don't think smell is even in the top 50 reasons that people end up with their partners, consciously or subconsciously.
If anyone's done a test of whether long-term partners generally adhere to those pheromone rules I'd consider that interesting, but initial attraction, scent-based or otherwise, isn't what determines long-term compatibility with a person.
