Yeast infections are a common type of fungal infection that can affect both men and women. They are caused by an overgrowth of the Candida fungus, which is normally present in small amounts on the skin and in the body. In men, yeast infections can develop on the penis, while in women they can develop in the vagina and vulva.
Yeast infections are not typically spread through sexual contact, but it is possible for a man to get a yeast infection from a woman if the woman has a vaginal yeast infection and the man comes into contact with the infected vaginal fluids. This is most likely to occur during oral sex or vaginal intercourse. However, it is important to note that yeast infections are not considered to be sexually transmitted infections (STIs) because they can also be caused by other factors, such as taking antibiotics or having a weakened immune system.
