Psychosocial development of heterosexual, bisexual, and homosexual behavior.

Relationships with overt adult Kinsey Scale scores (K) indicate that early sexual experiences are most closely related to K, followed in order by gender related and familial variables. A developmental model emphasizing social learning is presented. Interviewees were 7669 American white males and females. Elevated K (more homosexual scores) was found for females who had few girl companions at age 10 and few male companions at 16, had learned to masturbate by being masturbated by a female, had intense prepubertal sexual contact with boys or men, found thought or sight of females, but not males, arousing by age 18, had homosexual contact by age 18, higher K at 17, and higher first-year homosexual behavior frequency. Elevated K (more homosexual scores) was found for males who reported poorer teenage relationships with their fathers, had more girl companions at age 10, fewer male companions at 10 and 16, avoided sports participation, learned of homosexuality by experience, learned to masturbate by being masturbated by a male, had intense prepubertal sexual contact with boys or men, had neither heterosexual contact nor petting to orgasm by age 18, found thought or sight of males, but not females, arousing by age 18, had homosexual contact by age 18, higher K at ages 16 and 17, and had higher first-year homosexual behavior frequency. Behavioral bisexuals, those scoring between 2.0 and 4.0 on the K scale on the basis of overt behavior (0.7% of females, 1.2% of males), reported more arousal to heterosexual stimuli than did exclusive heterosexuals.
