There are only three events in your life that trigger oxytocin release: nipple stimulation (like
when I'm breastfeeding), labor (the oxytocin released during childbirth stimulates uterine contractions, which is why nipple stimulation might be suggested
when labor stalls, and also explains why sometimes, after you breastfeed me, you feel an increased expulsion of
lochia and maybe some cramping), and... orgasm!!
