I have an orange crust on my pubic hairs on the bottom of my ball sack. I don't know what this is. I am a very clean person. My wife also notices an odor that was not present before.
You have an infection, most likely in your hair follicles, which would be called folliculitis. Most can be treated with an antiseptic or antibiotic ointment. If it doesn't go away or reoccurs you will need to see a doctor to get treatment more specific to the bacteria that you picked up.
