Like condoms, PrEP is highly effective at preventing HIV when used consistently and correctly. You have to figure out what works best for you, and how comfortable you are with some degree of uncertainty. Some people will keep using condoms while on PrEP and others will decide to stop using them. If you are already using condoms consistently, and doing so makes you feel comfortable and protected, then keep doing what feels right to you. Many people struggle with using condoms consistently, which one reason why PrEP was developed. You have to decide for yourself what level of protection feels right and gives you the peace of mind to lead a sexually fulfilling life.
