APA Dictionary of Psychology

in women, the occurrence of more than one orgasm, without a resolution phase (see sexual-response cycle) separating the orgasms. Studies have estimated that as many as 30% of women experience this. Male multiple orgasm does not occur, because further arousal and response are not possible during the refractory phase following male orgasm. However, some men do carefully monitor and control their arousal and may experience the first elements of an orgasm, without ejaculation, more than once before having a complete orgasm, with ejaculation.
