Dancing should be a pleasant experience for everyone involved. Since dancing involves close contact proper hygiene should be one of the top priorities for the dancer of either gender. Make sure that you both shower (daily) and apply deodorant on a regular (daily) basis. Brush your teeth (dentists suggest after every meal); Gum is no substitute and can actually impede your timing. And please... go easy on the garlic.
Lastly, be mindful of those that have scent alergies. Excessive perfume or cologne could cause adverse reactions.
If these rules of ettiquette are adhered to, dancing for both partners will be much more pleasant, even before you start dancing.
