Hi, Thanks for posting in HCM. I understand your concern. Discharge from penis which is colourless and sticky is normal phenomenon when one gets excited. There are many triggering factors like watching porn which would exaggerate the symptoms, as in your case. It mainly occurs due to discharge as pre-ejaculatory fluid from the secretions from urethra and prostate gland. Experiencing pain in legs is again due to psychological fear associated with this. Such type of discharges doe not cause any weakness or problems with sexual activity. Sometimes, urinary tract infection could also be associated with excessive secretions from penis. Kindly get the following tests done and consult Urologist in case any abnormality is indicated in the report. 1. Urine routine examination. 2. Urine culture and sensitivity. Kindly relax and control your excitement by practicing relaxation techniques like meditation to keep your mind calm and healthy. Avoid precipitating factors like watching porn and excessive sexual acts and stimulations like masturbation. You can also practice behavioural techniques like stop and squeeze technique to control your erection and ejaculation. Hope the information provided would be helpful. All the best.
