Kinky cocktail experiment

So, I have this crazy idea that I want to try with my sub. I'm thinking of making him drink a cocktail that includes his own pee, cum, and even some of his shit. Yeah, I know it sounds disgusting... but also kind of hot in a totally messed up way, right?

Anyway, the question is - will he actually be able to stomach it (pun intended)? And more importantly... is it safe? I mean, throwing up is probably inevitable. But could there be any serious health issues involved? Like kidney damage or something?

I've done some googling but the results are all over the place. Some say its safe and some say its not. Thank you for your time
