Can I have sex when I have a yeast infection?

Yes. A woman most likely will not transmit a yeast infection to her partner during sex since it is NOT an STI. However, using protection is recommended if one partner has a yeast infection. That way, partners will not reinfect each other with the infectious form of yeast that may have caused the original outbreak. A male partner may experience some itching, but yeast infections do not grow on dry skin (like that of the shaft of the penis). Yeast organisms thrive mostly in warm, moist environments. Meaning that two female partners may want to abstain from sexual activity to prevent the reoccurrence of symptoms. Also, sex may aggravate the already existing symptoms of a yeast infection, but will not worsen an existing condition.
