Note. Percentages are within-column. Group means and inferential statistics are unadjusted. The percentages for “Two or more partners” represent the percentage of participants of that gender group that have had two or more partners, out of all participants in that gender group that have ever engaged in that behavior. The percentages for “Had a gender minority partner” represent the percentage of participants of that gender group that have had a gender minority sexual partner, out of all participants in that gender group that have ever engaged in any sexual behavior (i.e., sexual touching, or oral, vaginal, or anal sex).
