Piss taste?

When down on a new girlfriend for the first time and she had a pretty strong piss taste as well as her anatomy was significantly different than mine (I'm a lesbian and I know all are different, but wasn't expecting all the extraness) Im 24 so Definitely been around a few times but never experienced this. We were drinking earlier so I'm thinking maybe it was the alcohol kicking in? Just a little nervous for next time because it was super off putting and honestly made me gag a little. Advice?
