The New Paranoia

[Donald Q.]

The emails I’ve been receiving
lately are so disturbing to me: I think this line would have a nice flow if it was just 'lately are disturbing me'

strangers asking me  perhaps don't repeat 'me'? 
about the size of my penis,
my stamina,

wondering
about my lady,
if she is satisfied.  

Who are these
people?

How are they
privy to these things?    Both this stanza and the two before it don't need their line breaks, or even to be three individual stanzas, makes the middle too long.

And where were they
that first time I was alone
with Sherri Longfellow
when I went home out of breath
and she was witness
to all those stains
of embarrassment?  really like this last stanza, takes the poem from a gimmick to something personal 

Began a bit skeptical but i think you've got something good here which only needs a few adjustments; a bit of wry humor mixed with embarrassment and regret is a nice mix!
