I am 21 years old, I had a baby 3 years ago,and I've been with my boyfriend for 3 years. He's the only person I've been with sexually for 3 years. About a month and a half ago I caught a yeast infection and on my inner lip of my labia I noticed I had a grayish pinkish discoloration on the bottom of it (its is usually a brownish color). I used monistat and the cream that came with it and the discoloration didn't correct it self with the cream. My boyfriend and I do have sex and when we do it does get irritated and turns grey and I use A&D ointment and coconut oil on it and it turns back pink it won't go away and I don't know what this is
