Sex-role acquisition,parental behavior,and sexual orientation: Some tentative hypotheses

It was hypothesized that sexual orientation is not an aspect of sex-role socialization, but is acquired during a sensitive period from birth to 3 years through physical contact with adults. This is tentatively supported by evidence suggesting that (a) sexual orientation is highly resistant to change after adolescence; (b) infants respond to sexual stimulation and discriminate between the sexes; (c) gender identity is fixed between birth and 3 years of age; (d) during their infancy, homosexuals were psychosocially and presumably physically responded to as children of the opposite sex; (e) parents touch boys and girls differently. Stronger support for the hypothesis must be gained from longitudinal observation of parent-infant physical and social interaction and the infant's eventual sexual orientation.
