every women has discharge daily. Some have a lot to wear their underwear is wet and some only have a little to where it is a few white marks on your panties. Different times of the month can also mean more discahrge. An infection can cause more discharge and hormonal changes can also cause more discharge. As long as the discharge is not SMELLY or GREEN or CLUMPY LIKE COTTAGE CHEESE then its perfectly healthy and normal.
If you are always wet try wearing a panty liner during the day to absorb the moisture. But the wetness cannot cause a yeast infection. Overgrown yeast causes the infection. Yeast has to have the perfect enviornment to overgrow.
Sorry that your doc was so surprised. She really should have kept her opionion to herself. I think that was very inappropriate. but this day and age sex is more accepted. Thats probably why she was surprised.
But you arent dying, your just getting to know your body. Trust me there are tons of women who are going through what you are. There are more forums on here that can teach you more too like the vaginal health forum and yeast infection forum. But just ask and you can get the answers you need.
