Hi Mike.

I see nobody has responded to you and I don't think I'll be of much help so don't get your hopes up but we may have a bit of a similar situation. I suffer from scrotal tingling with occasional numbness. It doesn't cause numbness in my penis but I do sometimes get a feeling in my penis like its moving and in fact it is. That may not seem strange but obviously a mans penis moves countless times throughout the day but you're not supposed to feel it. I feel it moving all of the time like minor twitches. I believe for me these sensations are caused by the muscular mass that appears between my testicles when I have an erection.

So anyway, I know this probably isn't much help but maybe one of us will have a minor bit of insight that will help the other person solve his own puzzle.

Thanks and good luck
