Hi, I am sixteen years old and have sex a few times with the same person who I know is "clean", but the last time was about three weeks ago. This morning I woke up with an intense itching on my inner labia only on the left towards the bottom. I scratched it (I know, bad idea...) and now the area is extremely inflamed and feels tight like a knot. I have thought of a few causes, but I'm really hoping it is not sexual related since my parents do not know I am active. Some things I thought it could be caused by I usually wear thongs from Victoria Secret I shave the entire area every other day I have recently had a change in climate I have been wearing short shorts recently If there are any other things that could cause this I'd like to know and also know how to treat this Signed, Itchy and Embarrased
