BV question?

Chances are he would have no symptoms and you two could just be ping it back and forth. But some woman (including myself) has a very sensitive "eco-system" down there. I call it a eco-system so my husband can understand. But if we have ltoo much and he does not pull out his *** accually throws off the pH balance in my causing either BV or a yeast infection. My GYN told me that my body just doesn't like my husbands seman.
