Other quotes and descriptions were obtained directly from Savin-Williams. Ages of subjects and older partners when the sexual relations began are provided after the case numbers. A few subjects had additional sexual contacts with other men (Case 1 at age 14, then 15; Case 4 at age 17; Case 9, three more at age 16; Case 21, two more at age 17). Details were not recorded for these episodes.
Case 18 (boy 16, man 46). “I answered a personal ad. He wanted youth and I wanted age! I’m ‘slender, fun-loving, and cute’; he was ‘bearded, masculine, and worked out.’ We were together for ten months until I finally came to Penn State. I never lived with him. I’d go there to Pittsburgh maybe once a week or once every two weeks. He was very conservative and didn’t want to take me out publicly. He hates outward displays of affection and he didn’t want people to think he was my father. He sends me holiday and birthday cards. I think of him as my uncle. It was good for the time” (p. 164).
