Brief Summary:

Primary purpose of the study: to describe sexual behavior of Prep users, whatever mode of intake, ie continuous or on-demand; it has been shown in some studies, an increase of sexual risks in Prep users, and therefore an similar increase of STIs (sexually transmitted diseases); using a self-questionnaire, we'd like to evaluate sexual behavior before, and 6 months after, starting Prep.

Secondary purposes: to describe medical characteristics of Prep users (past medical condition, demographic characteristics, vaccinations, kidney function, serological results, urine and anal/pharyngeal swabs), clinical and biological Prep safety, STIs occurrence, and antibiotic prescriptions, continuous or on-demand intake, Prep indication.
