Pornwolf, I get the same reaction. I keep things low key most of the time, but when I get to a certain point with someone I tell them what I do.
Most people I come across are very intreagued by porn, especially internet porn. Infact, many of my friends ( who are not in the biz) brag to other people about their friends the "porn king" - of course when I meet these people I have to spend 30 minutes explaning what I really do.
It is not that glamorous.... well, at least most of the time it is not.
