When I was playing Big Bang Empire, I had a female teammate tell me the exact same thing about squirting. That it was basically piss. She told me that women have bladder issues (which I already knew) and that squirting was just them emptying their bladders. It's transparent because the body, in most cases, hasn't had enough time to cycle enough urea and ammonia to make it change color and give it an ammonia odor for the amount of water in the bladder. It's an interesting concept but one that was created by the porn industry. Tbh, biologically, female ejaculate would serve no purpose. It wouldn't aid in sperm swimming to an egg, since it would be outside the vagina. It couldn't serve as a lubricant, since the fluids are away from the Bartholin glands which actually produce fluid for penetration. It's just a myth. It looks hot in a porn movie or in VNs/RNs but it just ain't so. It's a mental aphrodesiac.
