How can i change the alkalinity of my vagina and my partners penis to prevent infections?

Vaginal pH: Is tricky and can be hard to maintain. Blood from periods, bacteria, yeast and semen can alter your pH from acidic to basic. I recommend gynatren probiotics to maintain normal flora and vaginal acidic ph. Men who are uncircumcised can harbor bacteria that can make you prone to get bacterial vaginitis. Hygiene and possibly referral to urologist may be last resort.
