How To Cure Pain And Soreness Of Vagina Observed After Having Intercourse?

I am a 19 year old female, 5 foot 5 inches, and weigh about 125 pounds. My vulva region has been hurting for the past two days or so. My mons pubis and labia majora have felt sore to the touch, although I don t see any lesions or weird discharge. I last had sex a week ago, but my partner has no STIs.
