Transition-marking behaviors of adolescent males at first intercourse

This study examined male transition-marking behaviors from adolescence into adulthood at the time of first intercourse. These include alcohol and drug use and sexual intercourse, and the companion behaviors of contraceptive use and planning of intercourse. The major findings were similar to those the authors described in a previous study as typifying female adolescents. Alcohol use at first intercourse was unrelated to use of contraceptives at that time, but was inversely related to whether the first intercourse was planned (i.e., those who did not drink were much more likely to plan). Planning was also positively related to contraceptive use, but the relationship was less strong than for female cohorts.
