All women secrete moisture and mucus from membranes that line the vagina. This discharge is clear or slightly milky and maybe somewhat slippery. When a woman is sexually aroused, under stress or at mid-cycle this secretion increases. It normally causes no irritation or inflammation of the vagina or vulva. If you want to examine your own discharge, collect a sample from inside your vagina - with a washed finger and smear it on glass to enable you to see it clearly.
Many bacteria grow in the vagina of a normal healthy woman.
Some of them help to keep the vagina somewhat acidic, which keeps yeast, fungi and other harmful organisms from multiplying out of proportion. These harmful organisms may secrete wastes that, in large amounts, irritate the vaginal walls and cause infections. At such times there may be an abnormal discharge, mild or severe itching and burning of the vulva, chafing of the thighs and occasionally, frequent urination. Gently wash your vulva and anus regularly and try to keep it dry. Also, don't use other people's towels or underwear.
