The new book, The Science of Orgasm, makes reference to oxytoxin and prolactin... how oxytoxin is generated in the pre-orgasmic phase of sex and prolactin comes in the refractory period. But they seem unaware of the possible benefits of generating oxytoxin without porlactin through sex without orgasm. With two caveats: They cite the odd case of a man who was able to have multiple ejaculatory orgasms without a refractory period and biochemically, without porlactin; and they cite reports that some women feel satisfaction after sex, even without orgasm. The sort of sex without (conventional) orgasm -- mutual and intentional -- discussed in Peace Between the Sheets remains off their radar.
