Every human being is continuously assailed by numerous stimuli, which he must interpret in order of importance, kind, and intensity. Because of our physiological and cultural uniformities we tend to make similar interpretations. Certain stimuli are usually interpreted as sexual in content and sexually arousing in effect. Such stimuli command attention and consequently are much used in the media of mass communication and entertainment.
In the years just after puberty, especially, many stimuli produce sexual arousal and even orgasm in males. The threshold of sexual response is low and selectivity relatively undeveloped. In young mammals one often sees general excitement transmute into sexual excitement, and this same ability is found in many young human males and probably in some females as well. With increasing age and experience the individual responds much more selectively and less readily, partly because of physiological deterioration and partly because of psychological fatigue: the desire becomes the familiar and the familiar becomes the monotonous. Often a novel stimulus of lower intensity than a familiar stimulus will produce a more rapid and intense response.
The interpretation of and response to various stimuli is often so subjective and complex that thus far the Institute for Sex Research has undertaken only limited and quite crude investigations of both contact (which we shall term “physical”) and noncontact (“psychological”) stimuli and resultant response. As far as physical stimuli are concerned, we have generally assumed some degree of sexual arousal and also a high positive correlation between the frequency of, preference for, and intensity of response from certain techniques. Nor have we investigated in any degree the so-called “erogenous zones,” except for a study of female genital sensitivity which is not synonymous with erogeneity. These are matters that will claim some of our attention in subsequent research.
Without becoming entangled in the definition of intelligence, we wish to observe that it is obviously involved in psychosexual arousal, and that we have collected information on the intelligence of the majority of males comprising this study. For the incarcerated males this information was obtained from the official records, which expressed the degree of intelligence either in terms of various psychometric tests or in summary descriptive labels such as “feeble-minded,” “moron,” “dull normal,” “above average,” “superior,” etc. When no official information was available (as was the case for nearly all the control group), we relied upon the brief descriptive notes we append to every case history at the time of the interview.
For practical purposes we condensed the data into four categories: feeble-minded (IQ-70), below-average (IQ 71-89), average (IQ 90-109), and above-average (IQ 110-f-). As might be expected, about half the control group fall in the average category and the others are more or less equally divided into above- and below-average. The prison group and the sex offenders present quite different distributions.
It is difficult to draw meaningful conclusions from these data. One can say, however, that of the tripartite groups the heterosexual offenders are the dullest (from 45 to 49 per cent were below the category of average), while the homosexual offenders were the brightest—roughly one third to two fifths rated as above-average.
The heterosexual offenders were joined by the peepers and by the aggressors vs. children to constitute the five dullest groups, while the five brightest include, besides the homosexual offenders, the incest offenders vs. children and the prison group. There is a strong correlation between intelligence rating and completed education. The five brightest groups also include the three with the largest proportions of college-educated, and four of the five groups with the largest proportions of persons with 11 and 12 years of education. Conversely the five dullest groups contained those with the poorest educations. This is not wholly a cause-and-effect relationship; certain forms of sample bias are also involved. Thus the homosexual offenders contain a large number of better educated because many were interviewed outside prison and came from a more favorable social milieu. On the other hand, the heterosexual offenders were, in comparison, far more rural and financially poorer.
The chief value of these intelligence data in this study lies in their explicating our findings concerning fantasy and psychosexual response.
Of the various noncontact stimuli—olfactory, gustatory, auditory, visual, and fantasy—we have concerned ourselves almost exclusively with the latter two. Our questions regarding visual stimuli were simple: we asked whether or not and to what degree the person was sexually aroused by seeing adults of the same and opposite sex, either in the flesh or in pictures, in various conditions of nudity and sexual activity. Naturally the questions and responses were highly interrelated; for example, a male who reported sexual arousal from seeing females also reported arousal from seeing nude female art, strip-tease, and representations of heterosexual activity. Because of this uniformity we decided to use in this present study only a few of the questions regarding visual stimuli. First, there is a general basic question: was the individual aroused, and to what degree, by the sight of other adult humans under ordinary conditions, as on the street or at a social gathering? It must be noted that even this seemingly simple question, “Does it arouse you sexually to see women (or men)?” is fraught with all manner of assumptions and qualifications about time, place, dress, physique, etc., and, to make matters worse, we considered frequency and intensity as equivalent. Despite these numerous and serious qualifications, and pending more sophisticated investigation, this question does afford worthwhile gross data. Second is the more specific question whether the individual was sexually aroused by pornographic photographs or drawings. The usefulness of this question is limited by psychologic conflict: the person may reply that he is not aroused, but is upset or disgusted—emotions which stem from a conscious or unconscious erotic response to the pornography. Nevertheless, such a reply was recorded as a negative. Because of the suggested connection between sex offenses and pornography we also inquired whether the person had owned pornography or had merely been briefly exposed to it. The third question is “visual” only in part: was the individual aroused by sadomasochistic pictures or stories?
The other area of psychological stimuli, fantasy, we have already treated in questions concerning sexual dreams and masturbation fantasy. In addition, we asked everyone we interviewed a more general question: “Are you aroused by thinking of the opposite (or same) sex?” This is the equivalent of asking, “Do you have sexual daydreams of the opposite (or same) sex?”
Before going on to describe our findings, one more complication needs to be discussed. While it is no surprise to find individuals who do not respond to specialized stimuli such as sadomasochism, or individuals whose inhibitions produce a negative rather than a positive response to blatant sexual stimuli, it is surprising to find substantial percentages of heterosexually active individuals who report no arousal from seeing or thinking of members of the opposite sex.2 Were these reports actually true, one would have to believe there were equivalent percentages of people who responded only to physical stimuli, who were never aroused by recalling past sexual experiences, and who never initiated sexual activity unless previously aroused by physical contact. Fortunately, we are not required to believe this. The truth of the matter is our questions were so phrased that only moderate to strong responses were counted as affirmative, and a mild response was almost certain to be recorded as negative. For people in the more educated upper socioeconomic level we used the phrase, “Does it arouse you sexually to . . . ?” while for the lower socioeconomic level we not infrequently used the phrase, “Does it make you (or get you) hot to . . . ?” This phraseology implies a considerable degree of sexual arousal to most persons. Indeed, if a person, when queried, asked for a clearer definition of arousal, we mentioned increased pulse, increased respiration, cutaneous warmth, etc., all of which are symptomatic of a rather intense or prolonged arousal:
Consequently, we cannot at present say how many heterosexually active individuals do not respond sexually to seeing or thinking about members of the opposite sex, and this statement also applies to the response of the homosexually active to the same sex. However, we can say definitely how many respond strongly and/or frequently, moderately and/or occasionally, and formerly (degree unspecified) but not currently; we can then provide a residual category for those who respond little or not at all. In this category of “little or none” we recognize that the “nones” are extremely rare in youth, but increase with age so that by perhaps the fifth decade of life the term “rare” is no longer appropriate, at least for males. A “none” report may be safely accepted when one notes that the person also no longer has sexual dreams or fantasy and has little or no overt sexual activity.
