Female orgasm via penile stimulation: a criterion of adequate sexual functioning?

This study assessed the extent to which a woman's ability to orgasm in coital situations with and without penile stimulation affects perceptions of sexual/psychological functioning. Subjects were asked to make diagnostic judgments about women described in written scenarios depicting heterosexual coital activity. Subject responses to all dependent measures reflected more positive/less pathological assessments for those situations in which the female in the scenario was described as being orgasmic via penile as well as manual stimulation, as opposed to those in which the female was described as being coitally orgasmic only with direct manual stimulation.
