Urology/Vibrating sensation on tip of penis


Hello Doctor,

I am a 26 year old male in good health and no major medical conditions.

About 3 days ago, after my girlfriend and I had finished having sex, I noticed a slight vibrating sensation at the top of my penis. It went away (or I didn't notice it) after a few minutes.

The next day, we had sex again (her on top, me sitting on the couch. Not sure if that's relevant), and I noticed it again for a few minutes. I went home, and noticed it while laying in bed. It lasted an hour or so and then I fell asleep. I did not notice it yesterday.

Today I noticed it while standing up. It occurred intermittently throughout the day. I did workout for about 45 minutes on an elliptical machine today, but didn't notice it until several hours later.

The "vibrating" sensation is in the tip, near the base of the glans, on the left side of my penis. It "pulsates" though not regularly, and does not line up with my actual pulse. It is very mild, but I do notice it.

Do you know what might be causing this?


Not exactly.  Strange sensations in the genitalia are notoriously hard to identify as the examinations are mostly normal.  Some type of nerve issue is possible such as diabetes or it may just be minor inflammation.  While I doubt its anything serious, check with your local physician.
