In my personal experience, squirting is like an extra orgasm you get from the g spot greatness. Does that pressure in your blatter and your shaking legs bring you pleasure? It can be overwhelming... But if you let yourself free that pressure and you squirt everywhere, you'll notice it's different than urine. But squirt juice does come from your blatter. An idea for a regular orgasm might be to get a vibrator and experience an orgasm solely from clitoral stimulation. I think both types of organs ar whereat but there is nothing like a vibrator on your clitoris - especially during intercourse. Good luck!
