Now having just commented that I don't hide it on the "where do you hide your porn" thread, I would have to say I don't go this far. Just in case someone stops over, or the landlord needs something. That would be awkward...
I once had a clean, "before" pic of Fi Stevens from one of Noise's clips as a wallpaper on my phone.
It felt terribly daring at the time, but it was only for a few weeks and I always kept my phone close, so it wasn't much of a walk on the wild side. Plus, anyone who had spotted it would only have seen a nice-looking redhead wearing all her clothes, so it was hardly a major outing risk anyway...
