You should do some more research, grow up a bit, and maybe try to “like” have sex more than a couple of times before writing about such a topic. First off, you start off lying. Either on purpose or you are just a lazy writer. The French research team did not do an ultrasound to find their bladders full before sex and empty after. It was the exact opposite.
“ The women started by peeing in a cup, as to empty their bladders and produce urine samples for analysis. To make sure their bladders were in fact empty, researchers performed pelvic ultrasounds. The women then retreated to private rooms to masturbate, either with or without sex toys, or have sex with their partners. As instructed, participants alerted researchers once they felt sexually aroused.”
At that point they did another Ultra sound to determine any changes. The end result was not conclusive by any means. They did however seem to think that most of the women were peeing, two of them they weren’t so sure about, and as anyone who has witnessed this act before can tell you, what is coming out is NOT urine. At least its not entirely urine. Urine has a fairly distinct odor in case you haven’t noticed. It also has a very distinct taste which I am sure you aren’t aware of either.
Furthermore, there are other studies which contradict this test.
“ However, recent research suggests that perhaps the ejaculate is an alkaline liquid that isn’t like urine, because it doesn’t contain urea or creatinine, which are normal urinary constituents. The fluid tends to be clear coloured and allegedly doesn’t stain bedclothes yellow.
Researchers have claimed that it contains some chemical ingredients similar to those produced by the male prostate — notably PSA (prostate-specific antigen). It is also said to contain two sugars: glucose and fructose.
In 2007, Viennese researcher Dr Florian Wimpissinger published an important study on two women who habitually ejaculated. (Incidentally, this surname is not some sort of joke. Dr Wimpissinger genuinely is a well-known urologist in Vienna.) He and his colleagues found that the ejaculate from these two females was chemically different from that of their urine.
In particular, it contained more prostatic acid phosphatase (PAP), more prostate-specific antigen (PSA), and also some glucose.”
“ Scientific research on the matter has been inconsistent. In a study published in The Journal of Sexual Medicine, researchers determined that the fluid emitted during orgasm showed all the characteristics of prostate plasma and not urine and concluded that this might be proof that our Paraurethral/Skene’s gland, where the fluid comes from, function as female prostate glands.”
