Are you skeptical about PrEP?
Downtime due to inevitable STDs does happen. Is unfortunate that some providers might continue being active while on recovery. Only once an escort I see regularly told me he got a positive test and asked me to get tested. He enjoyed his down time going to the museums in the mall, having friends over for dinner, etc. He told folks who were interested he wasn't available, saved their numbers and contacted them a week later he was back in the game.
Unless you prefer oral with a condom you can still catch STDs.
