Yeah...did that once before too...long story, but make sure your wife knows
that "let me know when you feel compression" doesn't mean the compression of

the cylinder (which of course means to any REASONABLE person, the pushing of
one's finger OUT of the hole :-) She forgave me, (and I her) in less than a
year.
