Hi, I am 25 and my girlfriend is 21. After we have unprotected sex, her vagina has a very strong bad odor that tends to stay with her for a long time afterward. It ruins her comfort level with sex. We are going to try rephresh gel to get rid of the smell. And I read that it could be caused because our ph levels are different. IS THERE ANYTHING WE CAN DO TO HAVE SEX OFTEN WITHOUT HER HAVING AN ODOR AFTERWARD?? Neither one of us have had this issue with other partners. Please help. Thank you.
