If you want to read more about breast milk without pregnancy, you can do a search for galactorrhea, or hyperlactation
a few quotes:
"... it is possible for both women and men to produce a milky discharge from one or both nipples without being pregnant or breastfeeding. This form of lactation is called galactorrhea."
"Galactorrhea is milky breast discharge that happens in women who aren't pregnant or breastfeeding. It affects as many as 1 out of every 4 or 5 women."
"The most common cause of breast milk production is an elevation of a hormone produced in the brain called prolactin. Elevation of prolactin can be caused by:
* medications
* underlying medical issues
* a tumor
* overstimulation of the nipples"
So, as you can see, it is most likely caused by overstimulation of the nipples. I mean, 4 or 5 hours a day is quite a bit ... although I can imagine it must have been heaven.
Oh and really do try to talk to your girl. Touching and caressing is not the way to go I think, just talk to her. Women mostly like to discuss things and even if she says she doesn't, let her know that you care and feel for her and that her feeling good is your number one priority. Forget about sex for a bit, concentrate on her mind and feelings. The sex will come when she feels secure and save. She's probably ashamed and worried about the breast milk. Reassure her that it is not a problem, I wouldn't make it into a sexual thing just yet, just make her feel at ease with you. Make sure she feels save, loved and cared for. That's what's most important to most women.
