I always had a drop or two on my nipples but it was usually due to heavy foreplay during sex. Nipple stimulation as well as hormones surgin in your body will make some women have a very small ammount of milk from their nipple.
yes i had a friend that done that and she had a tumor on her peturty gland and had to remove it she is ok now and went on to have a little girl that is 2 years old now
If you have elevated levels of Prolactin you can produce milk. Any nipple discharge, if not pregnant or nursing, should be reported to your doctor. Especially if you're not even sexually active.
I know of some females that experienced this same issue. As a result of miscarriages or abortion
