i am 14 years old and i have never had any sexual contact with anyone, not even kissing, so there is no possible way that this could be an STD of any kind. i just noticed today that my vagina suddenly became very irritated and constantly itchy, and when i looked, i saw that the outside of my vagina (labia majora) was covered in the same sort of sized spots as a pin *****, maybe a bit bigger, that are a kind of yellow whitish colour. there are quite alot, about a hundred, but they look a bit bigger because they are very close to each other. they are also spreading and moving up the side of the labia majora. im really frightened that it's serious and im too embarrased to tell my mum or ask a doctor to look, been there, hated that. please help if you know anything about this and what to do?
