I'm thirteen and yesterday I noticed my vagina felt very dry. I didn't think anything of it, until it started to itch. I then asked my friend and she told me I should probably look in a mirror to see if anything looked wrong, and it does. On the entrance to my vagina and all around it (on the inside of my labia, no where out) there is white,extremely dry stuff??? I also looked inside and the stuff is inside my vagina too?? I'm very worried, it doesn't really itch anymore but it is very very dry and a bit painful and actually (I washed my hands and everything before I did this) I touched the white stuff and some came off. I'm really scared, and I think it may be a yeast infection but I've looked up plenty of symptoms and none of them mention gross white dry stuff inside/outside the vagina. Anyone have any clue what this could be? I am not sexually active.
