No we're not talking about flashing the world à la Miley Cyrus or worse - Britney Spears. Many women wonder whether or not they need to wear underwear to bed. The answer is no. Well, a better answer is that it really depends on your personal preference. If you really feel bare "down there", then wear pajama bottoms or loose boxers. Wearing cotton underwear to bed is better than some of the fancier rayon/silk blends because it allows you to (ahem) breathe, but they also have a tendency to trap moisture and bacteria making you prone to developing some not so nice yeast infections. There may be certain times in your monthly cycle where you may find it necessary to wear underwear, but other than that try ditching them - your partner will thank you!
