Notes: SEM: Sexually Explicit Material; OR: unadjusted Odds Ratio; aOR: Adjusted Odds Ratio; CI: Confidence Interval; UAI: Unprotected anal intercourse; R-UAI: Receptive unprotected anal intercourse; I-UAI: Insertive unprotected anal intercourse; SDUAI: Sero-discordant unprotected anal intercourse. All logistic regression models were adjusted for age, HIV status, long term relationship status, age of first SEM use, positive and negative affect, social desirability, compulsive sexual behavior control, and internalized homonegativity.
