My ex used to squirt like crazy, that's why I don't believe it's piss. She was was different than any woman I been with cause she would literally squirt like 5 times a session and I'm talking a lot of liquid that's one reason I don't think it's piss cause you can only pee so much b4 you empty your bladder and she squirted a lot very frequently. And it didn't smell like anything
I had one chick who felt like she was gonna squirt but held it in cause she said it would feel uncomfortable because she squirted before and felt like she would be pissing herself.
