Male yeast infections are common and it is a myth that yeast infections in men don't happen. Generally speaking, these infections are likely to occur in the mouth or at the end of the penis, under the foreskin. A male yeast infection in the penis is known as balanitis, whilst in the mouth it is called Thrush. In rarer cases, yeast infections in men can occur elsewhere on the body such as the on the skin or in the intestine, but usually these only occur in people who are already quite ill and they are relatively uncommon in healthy males. Men with a foreskin are more prone to male yeast infections because the warmth and moisture underneath encourages the growth of fungus.
A male yeast infection is not classed as a sexually transmitted infection, because many people already have small amounts of the Candida fungus and people who have never been sexually active can still suffer from yeast infections. Whether or not male yeast infections cause problems depends on the situation. Candida likes warm and moist skin, and skin that is already slightly damaged. It also thrives on the high sugar in people with diabetes.
Men who get yeast infections invariably believe it's sexually transmitted. Although possible, most experts say that male yeast infections aren't usually the result of unprotected sex and often it develops in men who aren't sexually active. However, you have a regular female partner, it is quite likely that she will also be carrying Candida in her vagina.
