I would consider it, as I've heard urine is mostly sterile.
It depends. If I knew it were a thing of theirs or that they/ I really wanted to try it, I would say go for it. I might be picky about where they piss, though.
I might not be willing to drink their piss if I just barely met them, like it were a one night stand. Maybe piss on my mid-section if it were a one night stand.
If we'd been doing it for a long time, I probably wouldn't think of them as germy/ as the act as "gross" and might let them piss anywhere on/ in me
