Penile numbness from large butt plug?

I recently inserted a 3'' diameter plug for the first time (my previous record was 2.5''). I ejaculated very shortly after insertion because the feeling was so intense. During the ejaculation, I felt as if the left side of my penis head had been jolted or shocked. Three days later, the left side of my penis head still doesn't feel normal. It feels less sensitive and I'm constantly aware that it feels different from the rest of my penis (it's an area of about 1'' x .5'' that is affected).

Has this happened to anyone else? Did the altered sensation eventually go away? I assume this is the result of some nerve getting compressed from the large plug.

You may have pinched a nerve somewhere. I'm assuming you've already Googled your issue to see what came up...

How long did you leave the plug in? The perineal pressure has been known to cause a numb penis. This is not uncommon in bicycle riders if the seat isn't adjusted right or if riding was prolonged. It can also happen in women. In men it is known as "biker's penis" and I have occasionally had "bikers clitoris" feeling a bit numb after a half century. (That's 50 miles for you non-riders.)

Anyway, I doubt a short but very tight insertion would cause a problem, but prolonged insertion pressure could certainly cause numbness, tingling or altered sensation.
