As long as sex is dealt with in the current confusion of ignorance and sophistication, denial and indulgence, suppression and stimulation, punishment and exploitation, secrecy and display, it will be associated with a duplicity and indecency that lead neither to intellectual honesty nor human dignity.

The present study, then, represents an attempt to accumulate an objectively deter mined body of fact about sex which strictly avoids social or moral interpretations of the fact. Each person who reads this report will want to make interpretations in accor dance with his understanding of moral values and social significances; but that is not part of the scientific method and, indeed, scientists have no special capacities for making such evaluations (查看原文)
As a teacher in biology, the senior author had had his students bring him the usual number of questions about sex. On investigating biologic, psychologic, psychiatric, and sociologic studies to secure the answers to some of these questions, the author, as a taxonomist, was struck with the inadequacy of the samples on which such studies were being based, and the apparent unawareness of the investigators that generaliza- tions were not warranted on the bases of such small samples.

There are six chief sources of sexual climax... self stimulation(masturbation), nocturnal dreaming to the point of climax, heterosexual petting to climax, true heterosexual intercourse, homosexual intercourse, and contact with animals of other species. (查看原文)
Pre-adolescent sexual stimulation is much more common among younger boys than it is among younger girls. Many younger females and for that matter, a certain portion of the older and married female population, may engage in such specifically sexual activities as petting and even intercourse without discernible erotic reaction.

for scientific research allowed such laboratory investigation. In the higher mammals including the human, tactile stimulation is the chief mechanical source of arousal. but the higher mammal, especially the human, soon becomes so conditioned by his expe rience, or by the vicariously shared experiences of others, that psychologic stimula tion becomes the major source of arousal for many an older person, especially if he is educated and his mental capacities are well trained. There is an occasional individual who comes to climax through psychologic stimulation alone (查看原文)
a flow of blood into such distensible organs as the eyes, the lips, the lobes of the ears, the nipples of the breast, the penis of the male, and the clitoris, the genital labia and the vaginal walls of the female; a partial but often considerable loss of perceptive capac ity(sight, hearing, touch, taste, smell); (查看原文)
The most important consequence of sexual orgasm is the abrupt release of the extreme tension which preceded the event and the rather sudden return to a normal or subnormal physiologic state after the event. In the mature male, ejaculation of the liq- uid secretions of the prostate and seminal vesicles, through the urethra of the penis, is a usual consequence of the convulsions produced by orgasm in those particular organs, and such ejaculation usually provides the most ready proof that the individual has passed through climax. But orgasm may occur without the emission of semen This latter situation is, of course, the rule when orgasm occurs among pre-adolescent males and among females. (查看原文)
Behavior during orgasm... There is great variety among adult males; and, it is inter- esting to note, there is as great variety and the same sort of variety among pre adolescent boys. (查看原文)
(anger, fright, pain, etc. )may be the basic mechanism of sexual response. the pre-adolescent boy erects indiscriminately to the whole array of emotional situa- tions, Whether they be sexual or non-sexual in nature. By his late teens the male has been so conditioned that he rarely responds to anything except a direct physical stim ulation of genitalia, or to psychic situations that are specifically sexual. In the still older male even physical stimulation is rarely effective unless accompanied by such a psychologic atmosphere. The picture is that of the psychosexual emerging from a much more generalized and basic physiologic capacity which becomes sexual, as an adult knows it, through experience and conditioning (查看原文)
Without help from more experienced persons, many preadolescents take a
good years to discover masturbatory techniques that are sexually effective.

There are vaginal insertions which involve objects of various sorts, but most often they are finger insertions. Pre-adolescent attempts to effect genital union occur in nearly 22 per cent of all male histories, which is over half(55.3%)of the histories of the boys who have any pre-adolescent play. On this point, there are considerable differences between social levels (able 27). Three- quarters ( 74. 4%) of the boys who will never go beyond eighth grade try such pre adolescent coitus, but such experience is had by only one-quarter(25.7%)of the pre adolescent boys of the group which will ultimately go to college(Chapter 10) (查看原文)
The lower level boy has considerable information and help on these matters from lder boys or from adult males, and in many cases his first heterosexual contacts are with older girls who have already had experience. Consequently, in this lower level pre-adolescent contacts often involve actual penetration and the children have what amounts to real intercourse. The efforts of the upper level boys are less often success- ful, in many cases amounting to little more than the apposition of genitalia. With the lower level boy, pre-adolescent coitus may occur with some frequency, and it may be had with a variety of partners. For the upper level boy. the experience often occurs only once or twice, and with a single partner or two. These differences between pat terns at different social levels, eve... (查看原文)
The most remarkable aspect of the pre-adolescent population is its capacity to achieve repeated orgasm in limited periods of time. This capacity definitely exceeds the ability of teen-age boys who, in turn, are much more capable than any older males(Tables 33, 34, 48, Figure 36). Among 182 pre-adolescent boys on whom sufi cient data are available, more than half(55.5%, 138 cases )readily reached a second climax within a short period of time, and nearly a third(30. 8%) of all these 182 boys were able to achieve 5 or more climaces in quite rapid succession(Tables 32-34). It is certain that a higher proportion of the boys could have had multiple orgasm if the situation had offered. Among 64 cases on which there are detailed reports, the aver- age interval between the first and second climace... (查看原文)
While the sexual history of the human male thus begins in earliest infancy and develops continuously to its maximum activity somewhere between the middle teens and twenty years of age (Chapter 7), the steady progress of the development among primates, accelerated in a period of growth which is known as adolescence (查看原文)
Among most boys, the physical changes of adolescence come on more or less abruptly, usually between the ages of 11 and 14, and in that period their sexual activi- ties are suddenly stepped up until, within another few years, most of them reach the maximum rate of their whole lives(Chapter 7). Among most females, as the data in another volume will show, sexual development comes on more gradually than in the male, is often spread over a longer period of time, and does not reach its peak until a good many years after the boy is sexually mature (查看原文)
The mean age of first orgasm resulting in ejaculation is 13 years, 10 1/2 months (13.88 years). On this point, the male data are in striking contrast with preliminary calculations on the female. By 15 years of age, 92 per cent of the males have had orgasm, but at that same age less than a quarter of the females have had such experi- ence, and the female population is 29 years old before it includes as high a percent age of experienced individuals as is to be found in the male curve at 15. Precise data on the female must await the publication of a later volume (查看原文)
For the U. S. population, the sources of first ejaculation(Table 38, Figure 30)are in order of frequency, masturbation (in about two-thirds of the males), nocturnal emissions (in an eighth of the cases), heterosexual coitus (in one boy out of eight), and homosexual contacts (in one boy out of twenty), with spontaneous ejaculation, petting to climax, and intercourse with other animals as less frequent stimuli for the initial experience.
