Last night after urinating I was discharge with semens...I noticed white sticky fluid on tip of my penis. Thereafter I feel pain and unable to urine, then I masturbate to release my self which create a lot of pain in my kidney and testis as well. This usually don t happend to me but this case has been repeated to me after a gap of three months. Please advise
Thanks for asking in Chat Doctor forum Semen cannot get discharged unless you were sexually aroused. The white colored material which you noticed may be pre-cum which can be detected whenever anyone gets excited.  And pain and be seen sometimes if the act of masturbation/intercourse is prolonged too much without ejaculation.  So, please give details regarding any other symptoms/history of renal stones for further suggestions.  All the best & will be waiting for your details.
