PackingVegas: I'm a landlord, and usually I'm either alone in my office or alone fixing something, or mad at a tenant. So even though I wear pretty snug jeans usually (just more comfortable for me), it's just a general bulge, not a rod that shows.
One time though, I was on the phone (cell, with headset), and a tenant came in my office with a plumber, I had to go to his space, stayed on the phone with my buddy, who started talking dirty to me to get me hard, and kept telling me to show it, show it, show it... The tenant didn't know I had someone on the phone. I got hard, and was bulging a lot, just had a tshirt with the jeans, so couldn't hide anything without putting a hand in my pocket (which I did a few times). The tenant kept seeing me, and would actually lose his train of thought and stammer when he saw it. My buddy on the phone would laugh when he heard this, and say "Ha, he's looking now!" everytime.
It was kind of hot, kind of embarrasing, kind of unprofessional, but honestly it was fun, and the tenant never said anything about it afterwards. Besides, if there's a rumor going on about me in the building, being hung is a good one to have.
