Prostate Fizz

That feeling you get when you see or feel something that makes you horny. It often Pre-empts a Boner. It is felt in the perineum (gooch) for a brief split second. You can only experience this if you have a penis (to my knowledge) also known as penis base fizz.

I came across a pair of titties that I quite enjoyed and the result of this was prostate fizz.
