It doesn't matter whether the partner is only wet, the piss is swallowed or even pissed in the arse: Everyone sets the limits themselves.
Hardly any other sexual activity is affected by as many misconceptions when it comes to sexually transmitted infections as pissing. To put it in a nutshell: from a medical point of view, handling fresh pee is unproblematic. This also applies if the active partner is HIV-positive. This is because the viruses in the urine of an HIV-positive person are not sufficient for transmission. Otherwise, intact skin offers absolutely sufficient protection.
However, pissing on open wounds and mucous membranes or in the eyes can cause an infection with Hepatitis A and/or B cause.
