Signs - Omens - Portents with Aneros

I have had some many different indicators that the Aneros is 'doing something' while I build to an O or Super-O. I'm curious how many different ways we are all affected when the prostate is excited.

Recently, I have felt a very small space on the outside of my right thigh that will throb when things get going. A few nights ago, I had a sensation of a vibrator on medium in the back of my left knee. About one time in three, the souls of my feet will spasm (not curly toes) which first manifest as an ache and then a happy run of nerve endings from the feet to prostate.

I have seen others post about twitches in the face, lips and eyes which I have also experienced.

What are some of the other interesting places the Aneros has 'hit you?'
