[Occurrence of deviant tendencies in phalloplethysmographic and vulvoplethysmographic examinations in sexually...

The author demonstrates on four case-histories the presence of sexual deviant trends as the cause of sexual dysfunctions in conventional heterosexual relations in men and women and the irreplaceable part played by vulvo- or phalloplethysmography used for their detection. In a man treated for some time on account of impaired erectile potency and in a woman who visited the surgery with her husband and presented complaints diagnosed as secondary frigidity and anorgasmy, PPG or VPG examination revealed a homosexual orientation. Both these patients knew of their homosexual orientation but did not tell anybody. The mentioned male patient intentionally dissimulated homosexuality, the woman attempted in vain to achieve heterosexual adaptation. In two young men with primary disorders of erectile potency PPG examination revealed sadomasochistic tendencies. In the first one the impaired erectility created the impression of "debutant's failure" when starting a partnership, in the second one it seemed to be due to adverse psychosocial factors. During an interview following the examination both described spontaneously and in detail erotic dreams and masturbation fantasies with sadomasochistic contents. They were not aware of the association of their specific sexual motivation structure. It was typical for all four patients that they never disclosed previously their deviant sexual tendencies and only the specific situation during the PPG or VPG examination, which they had voluntarily after previous instruction, they were motivated to confess their problems.
