Yep. I checked that whole deal out at length a few years ago. The rapid spasmodic contractions of the vaginal canal can pump out up to a teaspoon of the vaginal lubrication upon orgasm. People confuse the two since urine often can be completely clear and odorless, and since we dont have the equipment to produce anything like semen or a prostate to squirt it out, there's nothing else it can be except the bladder lettin' loose. Women are more likely to loose bladder control than men anyway because of some slight difference in our urinary tract...we're more likely to pee from laughing, or cumming real hard. Sucks, but true.
