Hi, Thanks for posting your query. The clear transparent and sticky discharge from your erected penis when you are sexually excited is called as Precum or Prosemen. It is a gift or boon by nature. The passage of semen would be acidic due the residuals of urine and it is lethal to the sperms during transportation. To avoid the death of sperms, nature has this mechanism of a coating with this fluid inside your urethra transports safely all the sperms into vagina. It also lubricates the urethra for passage of semen and clears any unwanted waste. It is secreted by the glands in urethra and also by Cowper s gland near prostate gland. All the semen ejaculated into vagina cannot be retained as cervix will open only during delivery and abortion. Only few drops will be able to enter and do facilitate the sperms to meet the ovum. Remaining semen after titrating the vaginal PH , will come out. It is all normal. So not to worry. If you have not able to impregnate your wife even after 6 months of regular contact, then you and your wife consult your physician and get investigated and get treated if necessary. Wish you a family way as early as possible. Dr S.Murugan
