Well, apparently when the urthera is stimalated because it is so close to the bladder the muscles around the bladder loosen and even if you've emptied the bladder it will fill again with fluid and that is what you are releasing when you "squirt". Depending on the dilution sometimes it can have more pee fluid and sometimes it can have that milky white fluid which has a little bit of a smell that comes from the female prostate. Basically there is also incontinence which is having no control over your bladder but this is different. However if you have a urinary tract infection there will be even more fluid and if you do anything sexually you will literally sook the entire bed etc.
