What you need to have (we should all have them) is something called a "PORN BUDDIES" (refer to the British Show: Coupling).
Anyway: Porn Buddy: If you die, a trusted friend of yours has a key to your home, will go and take away ALL your porn videos & magazines. Thus, your family doesn't have to know or sort through your porn and will have a PURE and positive memory of you and your friend(s) get more porn! Its a WIN-WIN situation.

Note1: Coupling is from 2000, the internet was still NEWish so internet porn wasn't in the equation.
Note2: A friend died last year, she did photography and did take photos of me and my GF having sex... which of course, hopefully - her family just stored or destroyed the images.... I don't know, not going to ask. I would gather when they got to the kinky stuff, they exited out. She was a good person.
Hopefully in the future, my kids will KNOW not to go into Personal / Naughty folders... I think for most, a picture or two is enough for them to go "OH GROSS!" hehehe.... then say "holy shit, theres thousands of photos?!"
