Im only 20 and i was wonderin if it is normal for my vagina to be black inside and can it be changed also i don't know why i is clear slim coming out.

Get checked to know.: Hyperpigmentation can sometimes occur. The clear slime might be leukorrhea which is a normal vaginal secretion. If you have a change in color, texture, odor or amount of vaginal discharge & problems such as pain, itching burning with urination or sex or redness/swelling then it is best to see your gynecologist for evaluation & accurate assessment. Take care.
