This is hardly definitive,but:
I read that "squirt juice"(for lack of a better term),contains some urine.Some. It's quite diluted.
For me that explains why the smell and color are not like urine. I have never seen a yellow puddle on the sheets. Nor have I ever experienced a stanky urine odor during a prolonged DATY session,as the lady has repeated squirting Os.
What ThatSpot is talking about sounds to me like a legit Skene Gland situation, different from "regular" squirting.
