You know, Journia is right about this. Not all parents are conservative. I still live with my parents, they are fully aware of my fetish, and they are cool with it.
I myself didn't tell anyone (exept for a very trusted friend of mine) about my fetish, not even when I first started to post artwork on this forum. I used to do the exact same thing; clicking away this site (or any feett/tickling related site) whenever someone was passing by (our internet computer is in our living room). When I started doing comissioned work for MTJ of course, things began to change.
I just said that a publisher of adult fetish material wanted to have my work published, and their opinion was like "Oh, thats great! Well done!". In fact they were so open minded about it, I felt a bit of a fool for hiding it so long. 🙂
At some point my dad (he's an artist too, but not of the fetish kind) even bought me some hard to find Saudelli comics as a present :super_hap
I've been telling people ever since, and haven't encountered a single person yet who reacted negatively. My parents know, my brothers and sisters know, all of my former classmates, and a practically all of my friends.
Perhaps people are different here in Flanders than elsewere; I've got the idea that either they know what a fetish is, and are cool with it; or either they don't know, and don't care about it. 🙂
My opinion is that you very carefully test how open minded your parents are about things like fetishes, and if they are, carefully and gradually introduce the fact that you have one yourself. Don't rush it. 🙂
