…that male and female genitalia are referred to in different plural terms, linguistically speaking?

Female descriptors are usually referred to as a singular item, more specifically referred to in piece quantity.  A piece of ass.  A piece of pussy. 

Male descriptors seem to be referred to in the plural, however.  She wants some dick…some cock…it doesn’t seem very specific.  One of many will suffice.

Is it because penii are judged in stature by the linear inch?  And inches are plural?  Perhaps more importantly: does the rest of the world gauge penii in metric?  Inquiring minds want to know. 

And who decided that nugget of wisdom, anyway?  So long as there’s enough to work with comfortably for both partners, it seems to be a bit of an irrational criteria.  I have seen smaller women turn away more generously endowed men, which is totally understandable.  One person’s monster is another’s midget gherkin.  And why always linear inches?  I believe most women will agree that all girth matters.  The point is:  I don’t ever recall anyone saying "wow, I’d bet that chick has a really deep cervix".  I suppose one could, but I’ve never seen it happen, and don’t find it very probable.

Deez nuts I can at least get a grip on.  (Again, plural.)  I mean, there’s two of them (hopefully.  No offense intended to any potential uniballer Loungers). 

There is no moral to this story, other than humans are really quite silly, especially so in any matter involving any combination of sex and logical thought.  :getstones
