A little bit of science on this. Im no expert though, this is just from what I remember, so someone can correct me if need be;
Female squirting is liquid from a gland only around 50% of women have. “Skenes Gland” I think it’s called. The composition of the liquid varies, but generally it’s not considered “pee”. There may be similarities to urine, but it’s said it doesn't smell, taste, or look like pee. It is it’s own thing.
Male squirting on the other hand may just literally be urine. Through a study I saw had said it is “translucent and milky” in color, it had happened after the patient ejaculated, therefore, maybe the urine had mixed with semen?? I am not sure, but with an ultrasound study, it is determined that the liquid from male squirting does come from the bladder. Due to muscle contractions which feel much like an orgasm, it squeezes the bladder and sends out urine like liquid in a spray.
All in all… either matthew really did piss in Jin… or bro emptied his balls of unripe watery asf cum
WHAT!? something else can comeout other than c*m and p*ss?????? the fuck
