This research study will compare two experimental condoms with a commercially available latex condom. We will enroll approximately 300 couples into the study to use a total of 15 condoms at home. If you join the study, you and your partner will use five polyurethane condoms of each design and five commercial latex condoms during the courses of approximately 9 weeks. All study supplies, including condoms and lubricant are provided at no cost to you. You and your partner may each receive up to $150 for your participation.
