Watersports

My boyfriend has been begging to try new things in bed, one of the things he want to try is watersports, I'm not really into it myself, but I like to see him happy. Anyway it started with just me laying or sitting in the shower while he wees on me then he wanted to pee in my mouth and then piss up deep into my ass. All of those i was fine with (except the ass part that just felt weird).

Now he wants me to swallow the stuff!
Is it ok to drink the stuff, doesn't it have ammonia or something?

Drop that motherfucker.  If he was a normal man, he'd want you to pee on him, not the other way round.
