some girls squirt while others are just peeing. I've been with both. Some girls do in fact advertise as "squirters" when they are just pissing. That's a marketing ploy as squirting has become more popular in the past few years so some girls are trying to capitalize on it, even if they are not squirters. It's unfortunate.
I know I have been with real squirters because
-they squirt SOOOO MUCH
-only on obvious orgasm
-doesn't have a smell
-has no color
-after LOTS of squirting, they go to the bathroom to pee ( know because some of the don;t close the door and een sometimes I listed at the door to hear if she is peeing just for some sort of validation

). If ALL the squirting was pee, then how could she possibly have to still pee? I'm talking ounces upon ounces of squirting! No kidding. It would be impossible in those cases where she squirted more than even I pee and then still have to pee!
Other girls obviously were peeing. While others I suspect may have been squirting a little but some pee came out as they were unleashing it. If they really can squirt but they are trying too hard to let it out, then naturally some pee is going to come out of her bladder.
I'll be honest, it's a gamble. If you are turned off by pee, then I would suggest that, if you really want to experience genuine squirting, you stick with girls who have a proven record as a squirter and who squirts a lot. Now, that doesn't guarantee it's not pee, but your chances are exponentially better. But always realize that even if it's real "squirting" there will always most likely be traces of urine. That's scientifically a given.
