Hello,
The orgasm is usually associated with abrupt increase in blood pressure, pulse rate, contractions of pelvic musculature and contraction of
urethra in most of the women during sexual act in actual or fantasy or
masturbation height. The issue in your case is due to previous
cystitis, during which certain receptors get accommodation for the sensation of immediate bladder feeling even through some amount of urine due to bladder wall irritation.
Now when you are holding the urine for a period of time during the time period when you are away from washroom, even without sex feeling, those receptors send signals to the brain as of bladder distension and secondary spasm of pelvic musculature, contraction of the urethra as that happens in orgasm. It is best recommended to consult an expert
urologist for a uroflowmetry or
nerve conduction study of pelvic nerves for the precise diagnosis of the cause and treat accordingly.
Hope I have answered your question. Let me know if I can assist you further.
