pissing yes or no - S/M yes or no

Nothing is safe 100% guaranteed. If you have got as far as piss play with him you've very likely had some sort of sex with him already, so you are not going to be exposed to anything that you haven't already been exposed to. Once you've sucked his cock swallowing his piss adds nothing extra to any risk of infection so go ahead if thats what you enjoy. The chance of HIV transmission from urine is extremely low, there are far more dangerous things to worry about.
It is difficult to urinate with a full hard on, I dont know how they do that. The risk in pissing up the ass would be from any residual spunk being flushed out rather than from the actual urine.

So basically it doesn't any new risks so it is perfectly fine to do?

And this includes it being on him and in his mouth or in his ass?

Yes, remember the stories about sailors stranded in lifeboats, they survive by drinking each others urine.
Shit is another matter, you can get some terrible diseases from faeces, I wouldn't do that.
