I have been having a "minty" sensation feeling on my outside vagina lips up by my clit but on the outside! It doesnt hurt or anything and theres no redness, marks, or irritation! It kinda feels like someone ate me out with strong mint gum in their mouth lol. its been going on for about 3 weeks now...it comes and goes all through the day! What could this be? Google is no help (yes I'm sexually active...im married)
