I have constant itching in my vagina, and the outer labia is swollen. There's a burning sensation while urinating, which increases towards the end of urination. There's no thickness in the discharge but there's wetness at almost all times. I have been sexually active recently. Not long after which, I washed the area with a body wash instead of my vaginal wash. The sensation started right after that. I don't know what kind of infection this is. Please help.
