I agree with what's been said, there are some who may be pissing intentionally or otherwise but there's no doubt genuine squirting is different.
The type I've usually experienced is a clear, watery fluid from either clit or vaginal stimulation. It's not salty as piss, not yellow and does not have a strong odour.
Some women eject a different kind of fluid which is thicker and creamier in texture, this is in small amounts compared to the above. Seems to come from deeper inside and has a stronger smell (but not of piss).
On aw, the one I recommend is squirtynfun1981 whom I reviewed-
https://www.ukpunting.com/index.php?topic=196962.0She's a larger sized woman with some swinging experience and up for anything. If you want to experience squirting,
1) She squirts easily, some finger massaging of her clit is enough to get her going.
2) She squirts copiously, literally puddles of the stuff and she's reliably done it everytime I've seen her.
3) She squirts frequently, keeps going throughout the session non-stop.
Unfortunately for the OP, she does outcalls only and is based in Norfolk. She's willing to travel though if you pay cost of transportation or it's free if you pick her up. She only charges for the actual session, not including travel time and is reasonably priced.
