question: recently i have noticed that under my scrotum and on the sides of my scrotum, that some of the pubic hair in that area has this yellowish stuff on it that wont wash off of my pubes and is really hard to scrape off. There is no odor that comes from it and i have recently shaved in hopes that it will go away, but it just came back as my pubic hair grew back and it makes the hair look a little thicker, can u please tell me what this is and how to treat it?
