 OXYTOCIN AND MILK EJECTION
In the woman oxytocin release is often associated with such stimuli as the sight or sound or even the thought of the infant indicating a large cerebral component in this "neuroendocrine reflex".
Some of the dendrites have varicosities that suggest that they release oxytocin locally within the hypothalamus, a suggestion that is supported by several observations suggesting that local oxytocin is an essential regulator of the milk ejection reflex.
Finally there is mounting evidence for stimulatory effects of prolactin acting at the level of the neurohypophysis to play a role in oxytocin release possibly as part of a bidirectional feedback positive feedback loop in which oxytocin also facilitates prolactin release.

 Oxytocin in Women: The Bridge Between Touch and Sex
Nursing a baby produces oxytocin in both mother and child, and this is a major part of what initially bonds the mother and her baby.
Moreover, this hormone does not just create a sexual desire in women, coupled with estrogen it creates a desire to be penetrated (that is, it makes her want intercourse).Oxytocin increases the sensitivity of the penis and the nipples, improves erections, and makes both orgasm and ejaculation stronger; it may even increase sperm counts.
Not only does touch stimulate production of oxytocin, but oxytocin promotes a desire to touch and be touched: it's a feedback loop that can have wonderful results.
