Discoloration of my vagina

I am an 18 year old female, and the lips of my vagina are a dark brown, grey, and purple color. My boyfriend and I have sexual intercourse frequently and I just noticed it. I've never had this before

Hi!
The color of vaginal lips or labia can be dark brown due to your race or ethnic background. Other possibilities are trauma (repeated), infection, thrombosed blood vessels, dermatitis, eczema, Herpes, and low blood supply. Please consult a gynecologist and get this investigated. Take care!
