my vagina is really itchy off and on. its been like this for about a week now. wear it itches is read and slightly bumpy but looks like a rash. its all around the opening to my vagina and seems to be spreading. i had sex with a condom a little over a week ago and i also stated using a new body wash a few weeks ago. also i've been working out a lot more and more. i stopped shaving and im not cleaning down there with my body wash as much. i put lotion on it when it was just starting but not anymore. and its only gotten worse. what is going on?
