Mostly with golden showers I've been peed on and not drank pee. I don't know what you've done in this regard but you might ask your Domme if she will approach this slowly. Of course that she decides is her decision.

Oh I have drank pee just not large amounts. My owner liked to pee in my mouth but didn't mind if I swallowed or not. I found a way to let it flow into my mouth and out again without me being so unclassy as to spit. I'm glad that worked for him as while I'm okay swallowing some my stomach gets a bit queasy at the thought of swallowing a lot of it.

The only other thoughts I have is that the one doing the peeing should drink lots and lots of water and that its best to avoid really spicy foods as they make the pee smell and taste worse. Asparagus with a side of curry is not the right food for the domme to have before this play unless she really is a sadist.
