Only pregnancy can cause the final development that permits milk production.
Endocrine (Hormonal) Control of Milk Synthesis -- Lactogenesis I & II
Milk production doesn’t start out as a supply and demand process. During pregnancy and the first few days postpartum, milk supply is hormonally driven – this is called the endocrine control system. Essentially, as long as the proper hormones are in place, mom will start making colostrum about halfway through pregnancy (Lactogenesis I) and her milk will increase in volume (Lactogenesis II) around 30-40 hours after birth.
During the latter part of pregnancy, the breasts are making colostrum, but high levels of progesterone inhibit milk secretion and keep the volume “turned down”. At birth, the delivery of the placenta results in a sudden drop in progesterone/estrogen/HPL levels. This abrupt withdrawal of progesterone in the presence of high prolactin levels cues Lactogenesis II (copious milk production). Other hormones (insulin, thyroxine, cortisol) are also involved, but their roles are not yet well understood. Although biochemical markers indicate that Lactogenesis II commences approximately 30-40 hours after birth, mothers do not typically begin feeling increased breast fullness (the sensation of milk "coming in") until 50-73 hours (2-3 days) after birth.

The mother will begin producing milk during the last part of her pregnancy, then for the first week or so after the woman gives birth, her breasts produce colostrum which has antibodies and is very important for the baby to ingest. Following that, the mother will produce milk as long as the baby nurses.
A woman who has never been pregnant cannot produce milk, just like a cow who has never had a calf cannot give milk.

I know its possible for a woman to produce milk to nurse an adopted baby, it takes allot of time and patience and work though. As far as milk goes after delivery it is usually between the 2nd and 4th day after delivery the mothers milk comes in, what comes out of the breast before then is called colostrum, it is full of antibodies and is exactly what the baby requires the first few days of life.

I've heard of adoptive mothers breastfeeding their adoptive babies. Simply by using a breast pump and pumping quite a bit before the arrival of their baby. There's also a medication that you can use that will make a woman produce breastmilk without being pregnant.
I hope this answers your question.

During her pregnancy, a womans breast produces colustrum...that is a highly nutritious pre-milk liqiud, full of the mothers anti-bodies to pass along to her infant. After she gives birth, within a few days, her milk comes in. But a baby will always get the benefit of natures gift, colustrum, first. P.S. to answer your first sentence, yes, a woman HAS to have been pregnant to produce breastmilk.

Yes, the milk will continue to flow as long as the woman lets any child suckle.

There have been records of men breastfeeding motherless infants.
Anything is possible.
