Thinking nobody will find out somebody works in porn is pretty foolish and quite naive. It was almost impossible to keep it secret in the past and with the advent of the Internet is pretty much totally impossible now. Too many people get into the industry when they shouldn't. If one even feels that it might be even a slightly a bad idea for them they should stay away from it. It's one of those things where you better be totally sure or you shouldn't do it, because there is a good chance it could effect the rest of your life. People that get into it as the performers better be prepared for their parents, other family members, past, current and future friends, significant others, acquaintances, and fellow employees at a workplace to all find out about it and be ready to deal with it when that happens.
