What role does oxytocin have?
Many, I’m sure, but I know of two. Oxytocin is released in mothers during nursing. By flooding the mother’s brain with warm, loving feelings, it helps to foment a caring bond between the mother and the infant. This also happens to both sexes during orgasm, though the effect is more notable in women. After two or three orgasms with the same guy, most women are pretty much cemented in their feelings for the guy. But it’s the chemicals talkin’.
