    The existence of multiple orgasm in the human male has been discussed in the rich context of human sexual responses. Most males occasionally ejaculate more than once; but there are males who regularly do so, practically every time there is a socio-sexual contact. Of the white males who have contributed to the present study and who have had experience in intercourse, 380 have had a history of regular, multiple ejaculation at some period in adolescence or in adult years. Very few adult males are able to reach more than four or five climaces in any limited period of time; an occasional teen-age boy will reach six or more; and a quarter of the pre-adolescents for whom we have any record of orgasm were able to go beyond five, and in some cases to as many as ten, twenty, or more in a few hours’ time.
