One hundred and one pregnant girls aged under 18 years were interviewed to collect information about the development of their sexual awareness, attitudes towards relationships, and about their social context. The data show that the girls were likely to come from homes where the parents were divorced, where the mother married when she was under 21 years of age, and where her first child was conceived out of wedlock. Altogether 76 of these pregnant girls first had intercourse before they were 16 years old. The younger the girl at first intercourse the sooner it occurred in the relationship and for almost half of the girls first intercourse was unplanned.
Kathleen A. Early initiation of sexual activity is associated with more sexual partners, not using condoms, teen pregnancy, and sexually transmitted infection STI during adolescence.

A number of studies document a negative relationship between adolescent sexual intercourse and high school educational experiences and outcomes; yet, this research risks conflating the consequences associated with sex in romantic relationships with those that result when sex occurs in other relationship contexts. We predict that, compared to abstinence, intercourse in romantic relationships will have limited consequences for education, whereas the negative effects associated with sex in other relationships will be pronounced. We evaluate our hypothesis with two waves of data on nine measures of educational experiences and outcomes from the National Longitudinal Study of Adolescent Health. Our results are generally consistent with our predictions: the context in which sexual activity occurs substantially moderates the relationship between sexual intercourse and several education measures. These findings contradict the claims some abstinence-only curricula make regarding the link between adolescent sex and a plethora of negative outcomes.
