input: Dr. Havelock Ellis' 1933 book, Psychology of Sex, is one of the many manifestations of his interest in human sexuality. In this book, he goes into vivid detail of how children can experience sexuality differently in terms of time and intensity. He mentions that it was previously believed that, in childhood, humans had no sex impulse at all. "If it is possible to maintain that the sex impulse has no normal existence in early life, then every manifestation of it at that period must be 'perverse,'" he adds. He continues by stating that, even in the early development and lower function levels of the genitalia, there is a wide range of variation in terms of sexual stimulation. He claims that the ability of some infants producing genital reactions, seen as "reflex signs of irritation" are typically not vividly remembered. Since the details of these manifestations are not remembered, there is no possible way to determine them as pleasurable. However, Ellis claims that many people of both sexes can recall having agreeable sensations with the genitalia as a child. "They are not (as is sometimes imagined) repressed." They are, however, not usually mentioned to adults. Ellis argues that they typically stand out and are remembered for the sole contrast of the intense encounter to any other ordinary experience.  Ellis claims that sexual self-excitement is known to happen at an early age. He references authors like Marc, Fonssagrives, and Perez in France who published their findings in the nineteenth century. These early ages are not strictly limited to ages close to puberty as can be seen in their findings. These authors provide cases for children of both sexes who have masturbated from the age of three or four. Ellis references Robie's findings that boys' first sex feelings appear between the ages of five and fourteen. For girls, this age ranges from eight to nineteen. For both sexes, these first sexual experiences arise more frequently during the later years as opposed to the earlier years. Ellis then references Hamilton's studies that found twenty percent of males and fourteen percent of females have pleasurable experiences with their sex organs before the age of six. This is only supplemented by Ellis' reference to Katharine Davis' studies, which found that twenty to twenty-nine percent of boys and forty-nine to fifty-one percent were masturbating by the age of eleven. However, in the next three years after, boys' percentages exceeded that of girls.  Dr. Ellis also contributed to the idea of varying levels of sexual excitation. He asserts it is a mistake to assume all children experience are able to experience genital arousal or pleasurable erotic sensations. He proposes cases where an innocent child is led to believe that stimulation of the genitalia will result in a pleasurable erection. Some of these children may fail and not be able to experience this either pleasure or an erection until puberty. Ellis concludes, then, that children are capable of a "wide range of genital and sexual aptitude." Ellis even considers ancestry as contributions to different sexual excitation levels, stating that children of "more unsound heredity" and/or hypersexual parents are "more precociously excitable."

Answer this question "Who is more likely to experience it, males or females?"

Question: Obi-Wan "Ben" Kenobi is a fictional character in the Star Wars franchise. Within the original trilogy he is portrayed by Alec Guinness, while in the prequel trilogy a younger version of the character is portrayed by Ewan McGregor. In the original trilogy, he is a mentor to Luke Skywalker, to whom he introduces the ways of the Jedi. In the prequel trilogy, he is a master and friend to Anakin Skywalker.

Obi-Wan Kenobi is a main character in the animated micro-series Star Wars: Clone Wars and the CGI animated series Star Wars: The Clone Wars, voiced by James Arnold Taylor. In both series, Obi-Wan is a general in the Clone Wars, and he and Anakin have many adventures fighting the Separatists. The latter series highlights his numerous confrontations with General Grievous, his adversarial relationship with Dark Jedi Asajj Ventress, his romance with Duchess Satine Kryze, and the return of his old enemy Darth Maul.  In Star Wars Rebels, set five years before A New Hope, Obi-Wan appears as a hologram in the pilot episode "Spark of Rebellion". In the Season 3 episode "Visions and Voices", protagonist Ezra Bridger discovers that Obi-Wan is alive on Tatooine; Obi-Wan's old nemesis Darth Maul finds him as well. In the episode "Twin Suns", Maul is shown wandering the desert of Tatooine searching for Obi-Wan. Maul lures Ezra and uses him to draw Obi-Wan out. Obi-Wan rescues Ezra from dying from heat exhaustion and advises him to stay with the Rebellion. Maul appears and engages Obi-Wan in a lightsaber duel, but Obi-Wan mortally wounds him. With his dying breath, Maul asks Obi-Wan if he is protecting the "Chosen One"; Obi-Wan replies that he is. After Maul's death, Obi-Wan is seen watching over Luke Skywalker from a distance.  In Rebels, Obi-Wan was voiced by Stephen Stanton, who replaced James Arnold Taylor. Rebels creator Dave Filoni, who worked with the character during the full duration of Star Wars: The Clone Wars, said he considered asking McGregor to reprise and voice the role.
