Letter superscripts indicate if proportion in a given class is significantly different (p<.10) from other classes:
indicates significantly different than “Typical Debut” for females / “Single Behavior Debut” for males
indicates significantly different from “Dual Behavior Debut” for females / “Multi Behavior Debut” for males
indicates significantly different from “Early Debut” for females / “Early Anal Sex” for males
indicates significantly different from “Delayed Debut with Oral Sex” for females / “Very Early Debut” for males
