That might be true, except that it’s *inappropriately* sensual. Sensuality cannot contradict the Bas Melech essence. I don’t want to bring other hypothetical examples to illustrate the point, but HaMeivin Yavin.
Besides, even if Zumba were as you propose, it would be highly inappropriate to publicly engage in physical sensual marriage-enhancing activities. Marriage is private, and public Zumba, even in your perception, is therefore a gross violation of tznius to turn most anything to do with marriage into a group activity (certain types of lectures not withstanding). Again, I don’t want to bring other hypothetical examples, but HaMeivin Yavin.
