title: Initial stages of validation by penile volume assessment that sexual orientation is distributed dimensionally.
abstract: Kinsey concluded that homosexuality and heterosexuality were distributed dimensionally in the normal population, a significant percentage of whom experienced homosexual feelings. This conclusion has been ignored by most sex researchers. Twenty men seeking treatment for compulsive sexual behaviours reported a dimensional distribution of heterosexual and homosexual feelings, rated by questionnaire on 11-point scales. Their penile volume responses to 10-second movies of nude women and men were assessed. Significant correlations were found between individual subjects' penile volume and questionnaire assessment of heterosexual/homosexual feelings, validating their questionnaire-assessed dimensional distribution of their feelings. The finding was considered to provide the initial stage of physiological validation of the questionnaire, which in previous studies demonstrated a dimensional distribution of heterosexual/homosexual feelings in representative samples of medical students, supporting Kinsey's conclusion.
