I have excess white lotion like discharge coming from my vagina. There is no itch, odor, or burn. When I am intimate it coats my partner's penis . I always use protection and I am not on birth control. Have gone to the doctor and she did a test for yeast and she did not find it. What could it be? I have had pap smears and my doctor hasn't said anything abnormal about my discharge.

I have tried
Garlic -no effect

A little hydrogen peroxide -
No noticeable effect

Prebiotic vaginal suppositories. This made my discharge mucus like (almost like snot)
