How to protect clitoris during BA use?

Hi, I have a mild case of BV (I believe it occurred due to the heavy use of antibiotics and hormones during my IVF treatments). My doctor cancelled my embryo trader because of it, so I’m very frustrated by it and I really want to make sure I destroy any biofilm that has formed as I need to make sure it does not come back, or risk another cancelled embryo transfer.

I’ve read boric acid is better than antibiotics, as it destroys the biofilm. However, I’ve read reviews for different boric acid products and some say it burned their clitoris and now they have lost feeling.

I really want to try boric acid so I can hopefully prevent more antibiotic use, however I’m worried about boric acid side effects, especially permanent ones.

Any advice would be appreciated. Thank you!
