If you are getting yeast infections, it is safe to say that you have an overgrowth of canidida albicans. I would highly suggest you take some measures to thwart its progress. I am sure you have been on antibiotics at some point in your life... and they probably gave the canidida the upper hand. Antibiotics kill ALL the bacteria living in your body. The bad thing....... your body does have good bacteria. So now you have a prime enviroment for the yeast to take over. I would suggest that you go on a canidida cleanse and take probiotics. You can also eat yogurt, but get one that has more than one active culture. Here is a link to some good probiotics....
