I have that same issue with urine. yes its def embarrassing but from what i found it does happen - lucky us? I have an appt with my onco urologist in June and I will def ask about it. I'm about 7 months since surgery - I did kegels regularly before and after surgery and have no incontinence issues but maybe I'll start regular kegel exercises again to see if it helps.
This is what I found when I searched for it:
Leaking urine during orgasm after prostate removal (radical prostatectomy) is called climacturia and is a common, often temporary, side effect affecting up to 93% of men to varying degrees. It occurs because the prostate, which helps seal the bladder, is removed, and the remaining sphincter muscle may be weak.
How to Manage or Stop Climacturia:
Pelvic Floor Exercises (Kegels): Consistently performing Kegel exercises strengthens the muscles that control the bladder, which is the most effective way to reduce leakage.
Empty Your Bladder: Urinate immediately before sexual activity to minimize the amount of urine in the bladder.
Use a Penile Clamp: A penile clamp or a condom catheter can be used during intercourse to apply slight pressure and stop leakage.
Limit Fluids: Reduce fluid intake a few hours before sexual activity.
Medical Consultation: If symptoms do not improve after 6–12 months, discuss options with your urologist, such as a male sling or artificial urinary sphincter.
Key Takeaways:
It is not uncommon to experience this for 6 to 12 months after surgery.
Pelvic floor physical therapy or biofeedback can help identify and strengthen the correct muscles.
Do not hesitate to talk to your doctor about this issue; it is a known, manageable side effect
