Girls lose friends for having sex, gain them for 'making out'

And boys gain friends for having sex, lose them for 'making out.' Wish the study measured those who just remain silent about their relationships regardless of what they do. When did sexual relationships become so public?

"Early adolescent girls lose friends for having sex and gain friends for "making out," while their male peers lose friends for "making out" and gain friends for having sex, finds a new study that will be presented at the 110th Annual Meeting of the American Sociological Association (ASA).

"In our sample of early adolescents, girls' friendship networks shrink significantly after they have sex, whereas boys' friendship networks expand significantly," said Derek A. Kreager, the lead author of the study and an associate professor of sociology and criminology at Pennsylvania State University. "But what really surprised us was that 'making out' showed a pattern consistent with a strong reverse sexual double standard, such that girls who 'make out' without having sex see significant increases in friendships, and boys who engage in the same behavior see significant decreases in friendships."

The study relies on data from the PROmoting School-community-university Partnerships to Enhance Resilience (PROSPER) longitudinal study, which tracked two cohorts of youth from 28 rural communities in Iowa and Pennsylvania from 2003 to 2007 when they were in sixth to ninth grade and 11 to 16-years-old. Students were surveyed in five waves: in the Fall of sixth grade and in the Spring of sixth, seventh, eighth, and ninth grades. Kreager's study focuses on 921 students in the second PROSPER cohort who completed in-home surveys that included measures of sexual behavior.

As part of the PROSPER study, students were asked to nominate their best or closest friends in the same grade. In order to identify changes in peer acceptance, Kreager and his colleagues considered how many friendship nominations participants received in each wave.

According to Kreager, in waves where they reported having sex, on average, girls experienced a 45 percent decrease in peer acceptance and boys experienced an 88 percent increase. On the other hand, in waves where they reported "making out" without having sex, on average, girls experienced a 25 percent increase in peer acceptance, while boys experienced a 29 percent decrease in peer acceptance."
