Hi! I can answer that. As a woman who dated a man with persistant jock itch for almost two years. This man used creams adn even took Flagyl an antibiotic a few times. EVERY time we had unprotected sex, I would get a nasty bacterial infection. Every time it required me to go the the Dr and get on Flagyl. It was the most discusting thing I have ever had to deal with. I dont know if I helped, but yes you can give it to your partner and it turns up as BV.
