I ve had sex with only 1 guy, and probably 10 times or less. I ve noticed that my vaginal lip for lack of better words is beginning to darken. The left side of the lower part around the opening is really dark, and the left side of the left lip is getting dark too.. not black, but close, and only on the left side. Even near my clitoris is darkening! Why??? Is this normal or is something wrong? Is there anything I can do to make the color come back? I know my boyfriend has no stds.. he s been checked. Mature adult answers only please!!
