Participants will be blinded, with all condoms produced in plain foils with two-digit identifying codes, and role-based blinding will be conducted for study staff with the statistician and PI blinded. Participants will be trained in appropriate condom use, fitted condom sizing, study instructions such as only using study lubricant, and daily coital log completion. Participants will complete mobile-optimized, web-based home coital logs as soon as possible following any vaginal or anal sex acts. To assist participants in timely completion, there will be a daily check-in through Short Message Service (SMS) (via text message) with a reminder initiated if no sexual event has been recently reported. The coital log will include outcome measures for pleasure and for condom failure. The final visit survey will measure overall condom preference.
