with a co-worker, even one who seems trustworthy and sympathetic to the hobby.  Just play dumb and pretend you don't know anything.

I can't count the number of gossiping, duplicitous snakes I've run into after 30 years in the corporate world.  Even people I thought were on my team stabbed me in the back the first chance they thought it would do them some good.

If you want to end your career fast, just tell someone at work that you hobby.  And then count how long it takes for it to make it's way around the company.  If you're in a management position, they'll mail you your last paycheck after you've been escorted out.

Companies don't mess around these days.  All it takes is one female employee to find out that you see prostitutes and you're looking for a new job.

if you reveal you are a hobbyist.  Have you considered that this person may be setting you up?  What if somehow, someone got hold your browsing history on your PC, laptop, PDA, Smart phone, etc.

This may sound paranoid, but many sneaky things happen in the work place.  A friend was set up by an underling, in which she flirted with my friend for months and then charged him with sexual harrassment.  He was let go of his job - he was dumb enough to appear close to crossing the line and paid a heavy price by losing his job.

Don't be a fool, don't trust people at work with your personal life, they will use it to their advantage if you let them.  It's a dog eat dog world.  You'd be a fool to discuss it
