In speaking with friends and acquaintances who are employed in the adult industry, they have told me that almost every squirting scene in porn is piss and is not actually “squirting”.

There have been scientific studies done on "squirt" fluid and guess what - it's 100% urine. So no needing to admit anything.... Science! I actually think Jezebel posted on it a while back, so I'm surprised to see this article. **Edited to reflect link from IFLScience**
