 [ Symptoms ] when i masturbate i only produce pre cumclear liquid so i have masturbated for almost three years now i am 18 when i am masturbating clear liquid will develop from my urethra i assume it is pre cum i masturbate for 5 10 minutes normally and i start getting a great feeling building up which i assume is me about to ejaculate however when the feeling reaches the end i do not ejaculate and my penis stays in an erection unless i stop touching it then it goes down i have always assumed this was me climaxing [ Disease ] you should be ejaculating since you are not and i am assuming that you have never ejaculated in three years during masturbation there could be a problem one possibility is retrograde ejaculation   a condition where the semen is ejaculated backwards into your urinary bladder and not out of your urethra there are other possibilities of course but this cannot be solved on line this may not be an issue that can be solved by a your primary care provider so i suggest that you see a urologist
