Questions will inquire about STI status including a lifetime history and past 12-month diagnostic status for the following STIs: HIV, Gonorrhea, Syphilis, Chlamydia, Hepatitis C, and Genital Herpes. Participants will be asked "In the past year, have you taken PrEP (pre-exposure prophylaxis)?" ("0=No", "1=Yes, Daily PrEP", "2=Yes, On-Demand [2-1-1] PrEP", "3=Yes, Long-acting PrEP", "4=Not sure"). We will include ad-hoc measures commonly used in previous studies for single item assessments of lifetime, past year, past month, and past week number of partnered sexual experiences, sexual partners, and age of first partnered sexual experience. We will also include the ID Risk Behavior (BRAID) scale (e.g., "Had unprotected [no condom] sex with someone who was a one-night stand or someone you had just met?" "yes", "no"), sexual violence questions as recommended by the Centers for Disease Control and Prevention YRCSS standard national questionnaire.
