PSA, my mouth says no it fucking isn’t
Sexual ‘science’ still appears to be mostly done by misogynistic perverts who have an implicit bias against women actually enjoying themselves.
Does female ejaculate have some urea in, sure, it comes out of your peehole. However anyone with the slightest bit of actual sexual experience of squirting, who doesn’t just get what they know off youporn, will tell you, ejaculate is NOT pee. It doesn’t smell like pee, it doesn’t feel like pee, it doesn’t taste like pee.
So I suggest you wait four or so years, until you’re actually legally allowed to touch a woman, and find out for yourself before quoting ‘science’.
