IMHO - Its become such a topic of discussion that its become almost main stream (excuse the pun). I think this causes many woman out there to now want/feel they should be squirting. In many cases this leads to them be more likely to let urine go during sex or masturbation. In short, I think we need not argue that it is one or the other (urine or vaginal fluid), but realize that its one of 3 things. When you witness squirting in your personal life of elsewhere (err internet) it is
1) Just a chick peeing
2) A chick that filled her self with water off screen and is forcing it out on screen
3) A true build up of vaginal secretion that has pooled inside (likely blocked by your hand or penis) and is then released.
I have seen all 3. Id say that 50% of the time when I’m with my girl, the topic of pee comes up (I have to pee, I thought I was gonna pee, don’t touch me till I go pee). In her case she would NEVER let it come out during sex.. But thats her. I have also done the squirt technique and always, very quickly get to the sloppy, sloshy wet sound. That will last for maybe a minute and my wife is over it and pulls my hand away. As someone else mentioned, I think she wants nothing to do with releasing anything in front of me.. So she doesnt. If we ever got to a point where I said I wanted her to squirt, showed her what it was, explained what I was doing, and then asked her try, maybe she would. Lastly, she doesn’t have vaginal orgasms ever. :( Not sure if there is a correlation there.
