Guys can get yeast infections, but almost never from their female partner. Instead, a guy may get a red rash from yeast on the penis (called balanitis) because he’s been on antibiotics for a long time, he has diabetes, or he has an impaired immune system (HIV or another autoimmune medical condition). Symptoms often include itching and burning at the tip of the penis.
Yeast infection treatment is the same for a guy as it is for a girl; usually an antifungal cream that’s applied to the rash. If either a guy or girl has a yeast infection, it’s best to hold off on having sex until all the symptoms of the infection are gone.
