Teens who lose their virginity earlier than their peers are more likely to steal, destory property,shoplift or sell drugs than their virgin counterparts,according to one of the first studies to look at what happens in the lives of teens in the years after they start having sex.The study,in February's "Journal of Youth and Adolescence",found that those who had sex early were 26% more likely to be in trouble than those who waited. The protective effect of late sexual debut appeared to last well into early adulthood.Those who had sex later had delinquency scores 20% lower than their "on-time" peers.
