Timing of First Sexual Experience with a Same-Sex Partner: A Life Course Approach.

Abstract

Theories of sexual identity development recognize the initiation of sexual experience with same-sex partners (SESSP) to be a significant event in the coming-out process, yet the research literature lacks a population-based description of its timing and variation across population subgroups. Using data from the 2011-2017 National Survey of Family Growth and guided by the life course paradigm, we explored the timing and correlates of first SESSP among individuals (1425 women; 545 men) who identified as lesbian (n = 307), gay (n = 285), or bisexual (n = 1378) (LGB). Descriptive findings revealed that the median age at first SESSP was about 19years for lesbian women and gay men and one to two years later for bisexual women and men. Notably, initiation of SESSP occurred over a wide age range, particularly among bisexual men. Multivariable results indicated that the probability of first SESSP did not vary by demographic characteristics or family background among men. Among women, nativity status, family stability, and independent living were associated with probability of first SESSP. Coital experience predicted timing among both women and men. Tests for statistical interactions suggested that age at first SESSP was contingent on mother's education (women), sexual identity (men), family stability (men), and birth cohort (women and men). Our findings highlight the complicated nature of LGB sexual experiences, and we end with a call for greater effort to ensure that LGB individuals are represented in national surveys designed to provide data on sexual and reproductive health.
