Objective: This study sought to collect data on what adults believe co
nstitutes normal childhood sexual behaviors, and how variables, such a
s role, gender, and life experience might contribute to the formation
of one's beliefs. Methods: A survey describing 20 different scenarios
of children under the age of 13 interacting with themselves or other c
hildren in a sexual manner was administered to four groups of adults:
sexual abuse experts: therapists involved in a sexual abuse training p
rogram; medical students attending a human sexuality program; and grou
p facilitators of the human sexuality program. Results: Behaviors that
involved oral, vaginal, or anal penetration were judged by a majority
of adults to be abnormal sexual behaviors in children under 13 years
of age. Professionals working with sexually abused children rated cert
ain sexual behaviors as more abnormal than adults participating in a h
uman sexuality course. Both sexual abuse trainees and facilitators of
the human sexuality course showed more directional biases than other g
roups, with trainees always rating behaviors in the direction of abnor
mal and facilitators always rating behaviors in the direction of norma
l. Females also judged many of the sexual behaviors to be more abnorma
l than males. Conclusions: Role and gender significantly influence wha
t adults believe constitutes normal and abnormal childhood sexual beha
