Answered by Dr. Matthew J. Mangat 27 minutes later
Brief Answer:
Residual sperms are washed out by next urination.

Detailed Answer:
Hello XXXXXXX and welcome to HCM.
As an Urologist, studies suggest viability may not be more than next urination or one hour. Reason is, urine is acidic,and ammonia in urine, is also an added factor for destruction of the sperms, remaining in the urethra.
Hope your doubt is cleared.

I masturbated with Cetaphil, it entered my urethra and it's a little more difficult and painful to urinate. My shaft stings to the touch when I press where the head base is. It throbs and stings every now again and when I urinate, and now I can't stay errect. I hadn't had sex 6 months prior to this incident, can I rule out an STI?

I have a slight stinging feeling when I urinate. It feels like it comes from the bottom of the urethra. It lasts while urinating and for approx 20 minutes after. I also noticed a extremely red bump with a dark center on the head of my penis. I m not sure how long that has been there since I just noticed after the stinging started. I have a dr appt this week and wanted to know what to expect or what I should ask while there. Thanks.
