Yeah you will learn how to avoid to tell exactly what you do.
Since I have a mainstream business I always say that I'm doing some work related with that!
But I also have some "backup plans" like "I work online", "I build websites", "I do some part time translations".
I started in porn stuff when my kid was 6, now he is 10 and he don't know yet about my porn part-time.
I do all porn work ALWAYS on my laptop, no one touch it!
Anyway, I'm curious about if it is good idea to someday tell him what I do. Anyone did it? How it was?
PS: somehow it's sad, we talk about our job as something ilegal we must hide
