Answer:
I have had a simualr experience. I have not breast feed in many years. I recently remarried and my husband is a boob man. He sucks on my breasts and after 4 months I have started getting fullness in my breast, leaking, sorness. I found an article that over 100 years ago there were wet nurses. These women would be hired to breast feed a baby. After putting the baby to the breasts to suck the women would produce milk. Now days partners are finding it more sexy to suck on breasts for periods of time and alot of women will produce milk which is very erodic during love making.
