You wrote that if a couple had been doing the "exchanges" for awhile and one accidently causes an orgasm, it will change things for the worse. But you said such a couple would be releasing lots of oxytocin and be trusting and intimate- like an ideal couple in love, in other words. I would suppose that it would take a number of orgasms (if that) to cause any changes, as that is the case for couples in love, as was written before. Is a large amount of prolactin released or what? Just curious.
