First intercourse among young Americans

Area of Science:

• Sociology
• Demography
• Public Health

Background:

• First sexual intercourse (first coitus) is a significant developmental milestone.
• Understanding patterns of initiation is crucial for public health initiatives and adolescent development research.

Purpose of the Study:

• To examine the prevalence, age, and partner characteristics of first sexual intercourse among US adolescents in 1979.
• To identify demographic and relational factors influencing the timing and circumstances of first coitus.

Main Methods:

• Analysis of survey data from metropolitan-dwelling US women aged 15-19 and men aged 17-21 in 1979.
• Data collection focused on age at first intercourse, partner's age, relationship status, race, and planning of the act.

Main Results:

• 50% of women (15-19) and 70% of men (17-21) reported prior sexual intercourse.
• Average age of first intercourse was 16.2 for women and 15.7 for men.
• Women's partners were significantly older; Black individuals initiated earlier than White individuals.
• Women's first intercourse often involved commitment (going steady/engaged), while men's was more varied (friends, recent acquaintances).
• Planning of first intercourse differed by gender and relationship context.

Conclusions:

• First sexual intercourse patterns in 1979 US youth were influenced by gender, age, race, and relationship dynamics.
• Significant gender differences existed in partner age and relationship context at first coitus.
• Understanding these factors is essential for targeted adolescent sexual health education and support.
