Paragraph 2, line 2 read “I not going to devote this…” instead of “I am not going to devote this…” in this article as originally published.
Notes
The t-tests on the subjects’ responses to the other categories of female stimuli (pubescent and prepubescent females) can be interpreted in the same way as the t-test on subjects’ responses to the adult female stimuli. The result for the pubescent female stimuli was t(816) = 4.63, p < .00001, and the result for the prepubescent female stimuli was t(816) = 3.83, p = .0001. The foregoing results simply reinforce the conclusion that the subjects with same-sex experience were more arousable. The t-tests on the subjects’ responses to the three categories of male stimuli (prepubescent, pubescent, and adult males) are a little more complicated to interpret. The result for prepubescent males was t(816) = 2.70, p = .007, the result for pubescent males was t(816) = 3.53, p = .0004, and the result for adult males was t(816) = 5.46, p < .00001. These results could have arisen in two different ways: Over-40 subjects with same-sex sexual experience might have had greater penile responses to male stimuli because of their generally greater arousability, or because of a greater sexual interest in males, or because of both. These possibilities might be sorted out with multivariate analyses, but that would take us well beyond the purpose of this investigation.
