Background
A younger age at sexual intercourse has frequently been linked to adverse sexual health outcomes. Yet, little is known about its associations with healthy sexual function, and less still about the timing of pre-coital sexual debuts and adult sexual health.
Aim
We examined associations between an earlier sexual debut and subsequent sexual health, using broad operationalizations of each that capture pre-coital experiences and positive outcomes. Connections to sexual health risk and healthy sexual function were assessed through the lens of the dual-control model of sexual response.
Methods
Data on age at first sexual intercourse, first sexual contact, first sexual stimulation, and first orgasm, as well as sexual health risk and healthy sexual function were gathered from 3,139 adults.
Outcomes
Adverse sexual events (reproductive illness, infection, or injury affecting sexual activity; pregnancy termination and/or loss; non-volitional sex) and current sexual difficulties (Female [FSFI] and/or Male Sexual Function Index [MSFI] scores; Sexual Excitation and/or Sexual Inhibition Inventory for Women and Men [SESII-W/M] scores).
Results
When defined narrowly as first sexual intercourse, earlier sexual debut was associated with adverse sexual events, including non-volitional sex, pregnancy termination and/or loss, and reproductive illness, infection, or injury affecting sexual activity. However, it was also related to healthier sexual function, including less pain during vaginal penetration, better orgasmic functioning, and lower sexual inhibition. When sexual debut was broadened to include pre-coital experiences, earlier sexual contact, like earlier sexual intercourse, was associated with non-volitional sex. However, earlier sexual stimulation and orgasm were unrelated to adverse outcomes. Rather, these related to fewer sexual desire difficulties, and greater sexual excitation. Exploratory mediation analyses revealed later sexual intercourse and orgasm were connected to sexual difficulties through higher sexual inhibition and lower sexual excitation, respectively.
Clinical Implications
When sexual functioning is impaired, delay of both coital and noncoital debuts may warrant assessment, and sexual excitation and inhibition may be targets for intervention. To facilitate healthy sexual development of young people, non-coital debuts with and without a partner may warrant inclusion in risk management and health promotion strategies, respectively.
Strengths & Limitations
Although this research operationalized sexual debut and sexual health broadly, and examined associations between them, it is limited by its cross-sectional retrospective design and non-clinical convenience sample.
Conclusion
From a risk-based perspective, earlier sexual intercourse is adversely related to sexual health. Yet, it is also associated with healthy sexual function. Indeed, earlier sexual initiation may confer more benefits than risks when sexual debuts beyond intercourse are considered.
