Maybe. Can also be shafing from your cloths as they rub on your skin.
stress can increase vaginal itching but i'm not sure if it initiates it also.. some reasons of vaginal itching are low level of estrogen , any small infection in the vagina, inflammation or any reaction with any detergent, cream, soapetc.. don't stress out too much it makes you more susceptible to infections.. u can clean ur vagina witha cotten swab and a bit of luke warm water.. take care.
