GENITAL AND PSYCHOAFFECTIVE RESPONSE TO EROTIC STIMULATION IN SEXUALLY FUNCTIONAL AND DYSFUNCTIONAL MEN

To understand the sexual response patterns of men with premature ejacu lation and erectile dysfunction, the authors compared genital and affe ctive responses of sexually functional and dysfunctional men with 3 ty pes of sexual stimulation: an erotic video, penile vibrotactile stimul ation, and a combination of both. Genital response differed across bot h groups and stimulus conditions, with an interactive effect indicatin g that groups showed different response patterns depending on the stim ulation. Affective responses also differed across groups and interacte d with stimulus conditions. The combination genital and affective resp onse was superior to either alone in distinguishing men with no sexual problems from those with erectile or ejaculatory problems(or both). T hese factors were particularly useful in discriminating men with prema ture ejaculation from those with combined premature ejaculation and er ectile dysfunction.
