Had a lot of unprotected sex w/bf for 1st time this wknd, & got a yeast infect. why? on antibiotics 3wks ago for a sx, got a yeast infect, but cleared

Doubt : yeast infection. Not really a reason to get a yeast Infxn from sex. Having a lot of sex can cause irritation and itching. Unfortunately, women are taught if they itch, it's yeast. Rarely uis this true. Doctors many times treat women over the phone based on symptoms which only reinforces this false diagnosis. Have an exam and get cultures before you are treated for yeast
