Okay read this very carefully. I have found a cure for this problem with the vaginal tears. I seriously had this problem for a few years and went to different doctors to which they all said they had NO idea what it could be. Here it is.... and trust me on this it works because not only do I know why this happens but how to fix it. First off. It happens from Oral sex. Mouth to vagina. Spit to vagina. Any type of fluid from the mouth be it your own or your boyfriends/husband. There is so much bacteria in the mouth and the lip area and vagina area is VERY sensitive on a woman. Your spit or his spit (fluid ) from the mouth will cause tears and yeast infections.... sometimes extremely bad ones. Especially if the guy has bad teeth or gum disease or you have gum disease or any kind of food left in-between the teeth in your mouth, even if you cant see it, even if you think your teeth are perfectly clean. Its all bacteria and getting on your vagina which is causing this. I tried everything and was on yeast infection medications EVERY month until I found a cure to this. Have your man rinse his mouth out with mouth wash and you too if you lick your fingers and finger yourself or masturbate. Rinse with mouth wash before any kind of sexual activity whatsoever. I have even gone to the point where I now make him shower before having sex as well. But the mouth wash is the cure I promise you this. It worked for me! I don't get any more yeast infections and no more tears. Let me know how it all went for you girls~ Good Luck to you all
