If you've ever had a yeast infection, you know that it's not something you want to go through again. The good news is that you can do a lot to keep the healthy bacteria below your waist at a normal level, like wearing cotton undies, loose fitting pants, and avoiding douching altogether.
Staying dry down there is crucial in order to avoid the annoyance of a yeast infection, but that can be tough if you're a sexually active person. Natural lubrication that your body makes isn't going to affect your lady business, but if you use a personal lubricant that contains glycerin, for many women, that's a yeast infection waiting to happen, so make sure your lube is glycerin-free! Also, if you don't use condoms and your man does his business inside of you, make sure to use the bathroom after sex to help release some of the semen.
