Never trust anything from Wikipedia
Never trust anything from anywhere - Wiki, News, LPSG! Like I said - there's a dearth of coherent evidence scientifically, so shared experience is as good a source as any.
Oh, & you ejaculate back to your bladder if not externally( allegedly).
It wouldn't be hard to set up an experiment would it? Drinking only liquids with isotopes for a day, then wank yourself off under a CT scan. A random sample of 70 women, plus 30 women who say they ejaculate, & simply follow the fluid flow.
Surely it's that simple - any med students looking for a good topic for their doctoral thesis! Piss or Punani Punch!
I hope all these gushers swallow their partner's junk too! The epitome of selfishness if not. Lol.
