Sexual activities among minors are common and do not tend to damage participants. Whilst they play an important part in learning, their diversity refutes the common myth of "childhood sexuality" and "innocent sex play".

Sexual behaviour among youth

Effects

• Larsson, I. & Svedin, C. G. (2001). "Sexual experiences in childhood: young adult's recollections," Arch Sex Behav, 31(3):263-73

  In a 2002 study of 269 Swedish students, 30% of those who had a sexual experience with a peer before the age of 13 assessed the activity as having had a positive effect on them as an adult, 66% thought it had no positive or negative effects, and 4% reported a negative effect. Except one, all of the subjects who reported a negative effect were involved in coercive activities.

  "What's wrong with these things? "They make parents nervous," says Allie Kilpatrick, a social work professor at the University of Georgia who conducted a massive review of the literature on childhood sexual experiences, both wanted and unwanted, and administered her own 33-page questionnaire to 501 Southern women. Most of Kilpatrick's subjects had kissed and hugged, fondled and masturbated as adolescents, and more than a quarter had had vaginal intercourse. Her conclusion: "The majority of young people who experience some kind of sexual behavior find it pleasurable, without much guilt, and with no harmful consequences." A similar study of 526 New England undergraduates revealed "no differences...between sibling, nonsibling, and no-[sexual]-experience groups on a variety of adult sexual behavior and sexual adjustment measures."

  "The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. [...] After controlling for these genetic and environmental confounds using a quasi-experimental design, earlier age at first sex predicted lower levels of delinquency in early adulthood. [...]

  Although the current results are contrary to embedded assumptions, they are actually consistent with previous research. Specifically, three quasi-experimental (longitudinal or behavior genetic) studies that examined whether timing of first sex influences subsequent psychosocial functioning, controlling for psychological differences that precede sexual initiation, have all failed to find adverse effects for sexual timing. [...]

  The current study suggests that there may be positive functions for early initiation of sexual activity, in that the co-twin with earlier age at first sex demonstrated lower levels of delinquency in early adulthood. This result echoes a small but important body of previous research. In one of the first pieces of sex research, Kinsey et al. (1953) concluded that premarital sexual activity resulted in minimal "psychological disturbance" and may result in healthier non-romantic relationships and greater happiness later in life. More recent research has indicated that early sexual timing is associated with popularity (Prinstein et al. 2003); high self-esteem (for a review see Goodson et al. 2006; Paul et al. 2000); positive self-concept (Pedersen et al. 2003); high levels of body pride (Lammers et al. 2000), and increasing closeness to the same-sex best friend (Billy et al. 1988). [...] In the domain of adult sexual functioning, earlier age at first sex was found to predict greater coital orgasmic capacity in adult women (Raboch and Bartak 1983) and to discriminate sexually functional versus non-functional older men (age 64 years; Vallery-Masson et al. 1981). Women reporting an earlier age at first sex demonstrate less reactivity and faster recovery (as measured by cortical response) in response to stress (Brody 2002)."

  "Those who had forced sex were significantly more likely to be depressed or have suicidal ideation than those who had consensual sex and those who had no sex before age 18. There was no difference between the consensual sex group and those who had no sex before age 18. The level of well-being was significantly higher for the consensual group compared with the no sex before 18 group and the forced sex group. The latter two groups did not differ from each other on well-being. [...] Interestingly, the forced sex group and the no sex group were statistically indistinguishable in their level of well-being, while the consensual sex group was significantly more likely to have a higher level of well-being than either of the other two groups. This suggests that consensual sex before 18 years of age may have a positive effect, perhaps as an adaptive milestone of adolescent sexual development." This study was inclusive of both minor-minor relations and adult-minor relations; no distinctions were made.

  "Results supported the hypotheses that positively evaluated early sexual experiences would be associated with greater erotophilia, more acceptance of various sexual behaviors for self and others, and greater sexual satisfaction." (From abstract.)

Prevalence and diversity

Most prevalence data is limited to parentally-observed behaviour.

• Martinson, Floyd M. (1973). Infant and Child Sexuality: A Sociological Perspective. The Book Mark.

  "By twelve years of age, approximately one boy in every four or five has tried at least to copulate with a female and more than ten percent of preadolescent boys experience their first ejaculation in connection with heterosexual intercourse, according to Kinsey. Ramsey reported that about one-third of his sample of middle-class boys had attempted sexual intercourse."

• Ford. C. S.. & Beach. F. A. (1951). Patterns of sexual behavior. New York: Harper & Row.

  "As long as the adult members of a society permit them to do so, immature males and females engage in practically every type of sexual behavior found in grown men and women. [p. 197] [...] After reviewing the cross-species and cross-cultural evidence, we are convinced that tendencies toward sexual behavior before maturity and even before puberty are genetically determined in many primates, including human beings."

  In a 1999 study of undergraduate students, 5.2% of females and 12.8% of males reported having engaged in sex play with their peers involving genital contact before elementary school, and that 1.3% of girls and 4.0% of boys had engaged in sex play involving anal/genital insertion (with objects or fingers) or oral-genital intercourse before elementary school. By the end of elementary school, the numbers increased to 29.2% for females and 32.9% for males for genital contact and 12.3 for girls and 10.1% for boys for insertion or oral sex. Very little pressure and almost no coercion were reported.

  "Some recent studies of primarily White, middle-class children have expanded our knowledge of the types of sexual behavior observed in children without known or suspected histories of sexual abuse. These studies show that children engage in sexual play (Lamb & Coakley, 1993; Leitenberg, Greenwald, & Tarran, 1989; Okami, Olmstead, & Abramson, 1997); show interest in viewing the bodies of others, as well as displaying their own (Friedrich, Fisher, Broughton, Houston, & Shafran, 1998; Friedrich, Grambsch, Broughton, Kuiper, & Beilke, 1991; Phipps-Yonas, Yonas, Turner, & Kauper, 1992; Shafran, 1995); and have knowledge of sexual anatomy and function (Gordon, Schroeder, & Abrams, 1990a,b; Grocke, Smith, & Graham, 1995). Taken with the findings from earlier descriptive studies that document the occurrence of such sexual behavior as penile erections in male infants, genital manipulation and play, and masturbation (Kinsey, Pomeroy, & Martin, 1948; Kinsey, Pomeroy, Martin, & Gebhard, 1953; Moll, 1913; Spitz, 1949), non-abused children are suggested to display a wide range of sexual behavior. Behavioral differentiation by gender has been suggested, as genital manipulation and masturbatory behavior have been reported to be more common among boys (Friedrich et al., 1998; Gagnon, 1985; Rutter, 1971). Older children are suggested to be more knowledgeable than younger children about sexual behavior, pregnancy, and sexual abuse prevention (Gordon et al., 1990a), whereas hugging and kissing, self-stimulation, and exhibitionism are reported to be more common among younger children (Friedrich et al., 1991; Kinsey et al., 1948). The findings of some studies have noted an inverse relation between age and childhood sexual behavior, suggesting that the sexual behavior of children becomes covert over time (Friedrich et al., 1998; Friedrich et al., 1991; Gagnon, 1985)."

  "Eighty-five percent of young university women recalled erotic games and 44% recalled erotic games that involved boys [79]. Most remembered feeling sexually aroused or excited at the time. Most of the play involved exposing or touching the genitals. Insertion of objects in the vagina and oral contact was distinctly unusual. Other studies confirmed that most young adult students recalled early sex play that they viewed in a positive light as pleasurable and exciting [40, 80 and 81]."

Fetal/infant sexual capacity

• Giorgi, Giorgio, and Siccardi, Marco (1996). "Ultrasonographic observation of a female fetus' sexual behavior in utero," American Journal of Obstetrics and Gynecology, 175, 3(1, part 1), 753.

  "We recently observed a female fetus at 32 weeks' gestation touching the vulva with the fingers of the right hand. The caressing movements were centered primarily on the region of the clitoris. Movements stopped after 30 to 40 seconds and started again after a few minutes. Furthermore, these slight touches were repeated and were associated with short, rapid movements of pelvis and legs. After another break, in addition to this behavior, the fetus contracted the muscles of the trunk and limbs, and then clonicotonic movements of the whole body followed. Finally, she relaxed and rested.

  We observed this behavior for about 20 minutes. The mother was an active and interested witness, conversing with observers about her child's experience.

  Evidence of male fetuses' excitement reflex in utero, such as erection or ″masturbation” movements, has been previously reported.

  The current observation seems to show not only that the excitement reflex can be evoked in female fetuses at the third trimester of gestation but also that the orgasmic reflex can be elicited during intrauterine life. This would agree with the physiologic features of female sexuality: The female sexual response is separate from reproductive functions and doesn't need a full sexual maturity to be explicit."

• Yates, A. (2004). "Biologic perspective on early erotic development," Child and Adolescent Psychiatric Clinics of North America, 13(3), 479-496.

  "William Masters was an obstetrician before he became a sex researcher. He devised a game that he played while waiting for an infant to be born. He would bet that, if it were a boy, he could deliver the infant before the child could produce an erection. He won the game only half of the time."

  "He also noted that all girl babies lubricated vaginally in the first four to six hours of life. Infants were born ready and fully equipped. During sleep, spontaneous erections or vaginal lubrications occur every eighty to, ninety minutes throughout the entire life span. (Masters, 1975) Throughout life, sleeping sexual function remains far more reliable. While awake, our conscious anxieties take their toll.

  Masturbation culminating in climax may occur as early as the first month of life. The baby girl is the most enthusiastic and proficient. With unmistakable intent, she crosses her thighs rigidly. With a glassy stare she grunts, rubs, and flushes for a few seconds or minutes. If interrupted, she screams with annoyance. Movements cease abruptly and are followed by relaxation and deep sleep. This sequence occurs many times during the day, but only occasionally at night. The baby boy proceeds with distinct penis throbs and thrusts accompanied by convulsive contractions of the torso. After climax his erection (without ejaculation) quickly subsides and he appears calm and peaceful. Kinsey reports that one boy of eleven months had ten climaxes in an hour and that another of the same age had fourteen in thirty-eight minutes."

• Martinson, Floyd M. (1973). Infant and Child Sexuality: A Sociological Perspective. The Book Mark.

  "Before specifically discussing the affectional and sexual behavior of infants, we will more systematically and conclusively establish that infants have the somato-sensory capacity for erotic behavior. Boy babies are sometimes born with erections, and there is no reason to believe that the capacity for such marked physiological response develops any later in girls. In a study of nine male babies of ages three to twenty weeks, tumescence (penile erection) was observed at least once daily in seven of the nine. (Halverson, 1940). [...] Kinsey (1953, p. 142) reports one record of a seven-month-old infant and records of five infants under one year who were observed to masturbate. Twenty-three girls, three years or younger, appeared to reach orgasm in self stimulation. Kinsey's unpublished interview data contains notations from interviews with a small sample of two year olds and their mothers. One mother reported that her son had the habit of rubbing against a doll's head to masturbate. Another reported that her son's masturbating was deliberate, prolonged, and accompanied by an erection."
