Dear service user, Thank you for contacting healthcaremagic. I have gone through your question and understand your concerns. One involuntarily passes whitish fluid in urine, and more so while straining during stool passage. I understand that you are concerned about this. This fluid is largely the secretion of tiny glands in the way of urine tube and prostate gland. When a person squats in the toilet and exerts a little pressure, sometimes this pressure is relayed from the rectum to the prostate and urine tube (urethra), and a few accumulated drops of sticky white secretion accumulates and trickles down. In simple words, it is akin to if 10 drops of perspiration on forehead and when the 11th meets, it trickles down. The same thing happens in your urine tube. There is nothing to get worried about. You told that when you see a girl or having romantic ideas, you have discharge of fluid. When you have erotic stimuli (watching, thinking or smelling) the sexual excitement occurs. This causes series of changes in your sexual organs. There are tiny organs and glands (called bulbourethral glands and prostate gland) in the way of urine tube which discharges fluid during such excitement phase. This fluid is little in amount and having smell and mucoid consistency like semen. This is normal thing and having no harm to your body. Night emissions or ‘wet dreams’ are normal physiological events. This situation is just akin to a glass of full water to which you add more water, with the logical result that it overflows! This happens to semen too. If one neither has sex nor masturbation for long time, semen gets expelled in the form of night emissions, which is normal. This is not an illness or disease. No need to consult doctor for this. When one engages in regular sexual activity with partner or masturbation, the night emissions will be decreased or disappear. Hope I have answered your question. If you have any further questions I will be happy to help. Wish you good health.
