To what diameter can a typical human anus be stretched before it
suffers irreversible dilation?

Sorry, this is only a comment.

The "Geometry Question" attracted me, as I love Geometry. But when I
read the question, my naughty mind raced up to Astronomy.

You know, in planet Neptune, people there have expandable posterior
orifices. Flexible. People fom Neptune hide their valuables, like
money safes, or yachts, when necessary, inside their backs through
those openings. So if we can contact them Neptune people, we might be
able to find out how they can stretch theirs tat much.

Here on our Earth, not much. Even if we use Geometry to measure the
widest, it won't compare to those at Neptune.

Ticbol, you're killing me!

It occurs to me that we can measure anus size by examining our
politicians. Just see how wide  ___________________ (insert opposite
party politician name here) is and there you have it.

You know if the questioner also asks his math questions in the biology
section he's going to get some funny answers because microbiologists
think multiplication and division are the same.

I remember an old joke that goes...   "How are the startship
Enterprise and toilet paper alike?"  The answer is that they both
circle Uranus in search of Klingons.

If this metaphorical connection were to hold true, then the average
Klingon infested anus could be as big as Uranus, which I think is
about 4-5 Earth diameters.  So, bonnisimo, my submission is
5-Earth-Diameters, or about 40,000 miles.  I'm just glad its Uranus
and not Myanus!!

u get answer only by survey becoz it varies from person to person.

U r some random person oi, how did u even think of putting that
question on here, nd i agree with tha dude b4 me...it wood definetly
depend on the person oi!!k toodlez...
