I like it ,i find it a turn on that i have given her a more intense orgasm than usual [i concede that it may not be my doing at all ,and may have occured had she masturbated ,but i like to believe that it was me]
Leg said:hmm so is it urine or not? if it is urine, i figure we should link this thread together with the golden shower thread![]()
EternalX said:What he said though is what i thought all along. Him and other doctors had tested a bunch of women that had this ability and in a LARGE case of them the liquid come out was in fact urine...
Research in the 1980s and 1990s finally began to analyse the chemical of fluids released in female sexual response in some depth, focussing on the presence of prostate-specific antigen (PSA) manufactured in the female prostate, and the concentration of other substances (urea, creatinine, glucose, fructose) in relation to their usual concentration in urine, usually achieved by taking samples of pre-orgasmic urine, post-orgasmic urine, and female ejaculate.
Analysis carried out by Whipple and Perry in the early 1980s established substantially higher levels of prostate-specific antigen and glucose, and substantially lower levels of creatinine and urea, in samples of ejaculatory fluid than in samples of urine from the same women.[11]
A simple marker test carried out by Whipple, in which the characteristic odor produced by ingesting asparagus was clearly present in subjects' urine, demonstrated that this was not present in female (and indeed in male) ejaculate, demonstrating a difference in the two fluids.[12] This is similar in its result to the much reported experiment in which a student of Edwin Belzer took a drug to dye her urine bright blue, and found that whilst her urine became strongly coloured as expected, the fluids she ejaculated during masturbation showed only a slight blue tinge or no colour at all.[13]
A study by F Cabello Santamaria analysed urine for prostate-specific antigen (PSA) using Microparticle Enzyme Immunoassy and found that 75 per cent of the sample showed a concentration of PSA in postorgasmic urine samples which was not present in preorgasmic urine samples.[14] The fluid collected at the point of orgasm (distinct from the urine samples) showed the presence of PSA in 100 per cent of samples. Cabello believes his research to confirm his hypothesis that all women are capable of ejaculation, but the amount of fluid expelled from the female prostate, or the direction in which it is expelled (towards the bladder), mean that it is not always perceived. (Cabello notes that retrograde ejaculation is also an occurance in some men.)
Cabello provides his own summary of those whose work he concludes has proven the presence of PSA in females fluids: "...we have all those authors that try to prove that women emit a certain fluid, different from vaginal lubrication, during their sexual response (Grafenberg, 1950; Sevely & Bennet, 1978; Belzer et al, 1981; Perry & Whipple, 1981; Addiego at al,. 1981; Sensabaugh & Kahane, 1982; Belzer et al., 1884; Zaviavic et al., 1984; Stifter, 1987 etc). Thanks to this last group, the presence of prostate acid phosphate and fructose in the supposed female ejaculation, elements normally present in male ejculation, seems proven".[15] According to Whipple, it is Zaviacic in his 1999 book on the human female prostate[16] who provides "the most complete enzyme histochemical, exocrine, and imunohistochemical studies on the female prostate and the analysis of female ejaculation".[17]
Despite this body of evidence, it cannot be said that the issue is without complications. Dr John Perry has attempted to analyse findings further, to propose that there may be more than one type of sexual response in women which involves the emission of fluid. 'Pure' female ejaculation involves secretions of the female prostate; alternatively, 'gushing' involves a much diluted form of urine; or the two phenomena may occur in combination.[18] Whilst larger volumes of fluid may indicate that it involves the expulsion of dilute urine, its chemical composition implies that it is a distinct part of sexual response rather than ordinary urination. An experiment recorded by Dr Gary Schubach involved female subjects engaging in sexual stimulation then having their bladders drained with a catheter. After this draining, seven women still expelled 50 -900 ml of fluid in sexual response, fluid that showed "a greatly reduced concentration of urine and creatinine (the primary components of urine). The clear inference was that the expelled fluid is an altered form of urine, meaning that there appears to be a process that goes on during sensual or sexual stimulation and excitement that effects the chemical composition of urine".[19]
It is reasonable to suggest that the most far-reaching conclusion to be drawn from this is that it is not credible to expect the expulsion of urine (especially if chemically altered, vastly diluted expulsions from the bladder are still to be described as urine) to always be kept completely out of scenes of sexual activity and response.
