This business is surviving on something...and it ain't just me. I would surmise that a lot more of our friends, associates, co-workers and the like hobby more than any of us care to [openly] admit. No one talks about it because of the taboo factor and the stigma (you're not cool if you're paying for it).
I do find it funny how co-workers occasionally throw a running jab at the hobby. A guy may go [responding to a question about plans for the night] "Oh, man. I dunno. I'll probably just buy some beer an' a pizza and call up a hooker."
Of course, when one says that, they're trying to be coy and nonchalant, but...this might ACTUALLY be his plans for the night.
The comment draws a chuckle or two from other guys, who may...MOST LIKELY...are probably thinking to themselves the SAME THING.
