If you don't have any diseases can your partner get any if doing unprotected anal sex? Like say you don't have a disease and you have unprotected anal sex is there a risk of them getting a disease from it ?
There is always a chance of passing different bacteria through unprotected anal sex that is why you should always use a condom and you should never go from anal to vaginal without changing condoms and washing well first because you can introduce unwanted bacteria into the vagina that can lead to other problems.
