well i can tell you that you are not the only guy out there that likes lactating women, an ex had a porno of a woman squirting milk as she climaxed.

As a mom, who breastfed her babies, it was as much of a turn on as sitting down to a meal with the family. I was feeding my kids as nature intended.

Lixy had a great explaination (Good job Lix)and YES men have breastfed babies before . and adpotive mothers have too, it just takes A LOT of nipple stimulation and the right mix of herbs and hormones.

to further the "squirting" answer, it can be caused either by the mother hand expressing milk, or pumping with a breast pump, into a bottle, for the baby to drink if the mother has to be away (such as work) and cannot feed directly.

OR

I think this is more of what you were thinking as a sexual nature. Pregnant, post-partum, or breastfeeding mothers can leak or "squirt" milk upon sexual climax. this is due in part to a hormone called Oxytocin. It is released at sexual climax to cause uterine contractions, or to start and keep a woman in labor, and also when a mother is breastfeeding her baby and the milk "lets down" or starts flowing easier out of the breast into the baby's mouth as the baby sucks at the nipple and areola. So because of the oxytocin release at climax, it also triggers the let down reflex and the milk can be forcefully ejected, or squirted.

I am a big breastfeeding geek and advocate, any more questions, feel free to ask!
