An attempted humorous pluralization of the word "penis". As with other words from Latin that end with "is", such as "crisis" and "neurosis", "penis" changes the "is" to "es", forming "penes", as "crisis" changes to "crises" and "neurosis" to "neuroses". Only urologists and a handful of other professionals use the word "penes", however, so it is best to stick to the English plural, "pensises".

The penis is the male reproduction organ and the reason I believe there is a God. The penis is a remarkable peice of workmanship. Completely thought out - for example, look at the head..it is shaped for easy entry, soft to cushion the blow - it even has a "seam" on the underside to avoid suction. Perfect.
