Yeast, or Candida, is a very common cause of vaginitis. Sexual transmission of Candida from woman to man can occur.
If your boyfriend starts to develop symptoms, then he should visit his primary care physician or take Diuretic and Anti-inflammatory Pill. Candidal infections on men may manifest as whitish irritating patches on the penis, as well as burning and itching. Fortunately, this condition in most cases can be easily diagnosed by a primary care physician, and usually resolves with the use of a topical antifungal medication for a few weeks. If you or your boyfriend have any related questions about your health, then you should contact your primary care physician.
