We are conducting a study to see what kinds of products people would prefer to use before anal sex, a douche, an insert, or a suppository. Participants will be asked to use each product for a period of 1 month each and complete surveys about their opinion and experiences with each one. There is no active drug in any of the products being used. The study lasts about 3 months, and you will complete a total of 8 visits. Physical exams and HIV/STI testing will be provided at no cost. If you complete all study visits, you will be compensated up to $700 for your time. If you are a man or transgender woman, ages 18-35, you may be eligible to participate. Call (205) 996-4405 for more information.
