Surprise piss play while edging
I am a disabled guy in his 40's. For over a year now, I have been having an embarrassing problem. Whenever I edge for more than thirty minutes, and as my shaft pulsates as if to spurt forth a load of precum, a stream of urine suddenly shoots out of my erect penis. This sometimes happens after I've been spurting out loads of precum, and sometimes before doing so.
I was not into piss play before this started happening, but I now know the appeal it can have. It doesn't really disgust me because I only drink water nowadays, but it is distracting. I've had to cut edge sessions some hours short because I would not want to deal with the huge mess. I make sure my bladder is empty before edging, and still I am dealing with jet streams of clean piss. I really do not wish to return to the days of quick wanks and instant loads.
Before consulting a physician, I'd like to know what the fine gentlemen of this subreddit have to opine. Thank you very much for your attention.
