 [ 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 ] hi next step in my opinion is to investigate you cortisol levels to check for cushing syndrome so i recommend low dose dexamethasone suppression test or a 24 hour urine collection to quantitate cortisol levels also check gfr and blood electrolytes i can be with you for follow up good luck
