<human>: Can you provide a brief overview of the text?

The actual mailing took place a few weeks back. However, I just found out about it today.  

So I work for a company with older clients some of whom don't have email and part of my job is to respond to client questions.  A client called in asking me about the history of the caduceus. Not exactly on topic for our company but it was quicker and easier to tell him I would send him info than bother with explaining that is not my job.

So, I googled and printed a few pages on the caduceus.  Not caring about the details I didn't read them and just grabbed the pages from the copy room printer, tossed them in an envelope and mailed them.

Today I got a letter from this client calling me 'a sporting woman' and letting me know that I can mail him pictures of naked woman whenever I please.

What? What? What did I mail him? I have no clue. None!  Hoping I don't lose my job and no one else finds out.  

I went back and looked at what links I think I printed.  I cannot find what I could have sent to make him send this. Only thing I can think of is some doofus in my office might have printed naked pictures at work and I grabbed them.
<bot>: Didn't look at pages I picked up from copy room printer and mailed them to client. Had naked pics in there. Nervous for my job.
