Dude, how much hidden porn do you have stored on your hard drive that you don't want her to accidentally stumble on?
When my husband's PC breaks down, he goes to the library to check on-line stuff, even though I would totally let him use mine. The fact is, I have mine so skinned to my tastes, he doesn't even know how to load the web browser! (Object Dock 2 -- all the icons are hidden under tabs, and he's so used to clicking icons on his desktop, I don't even think he knows HOW to use the start menu to find anything).
lol Hidden porn? None, she knows right where it is. Why would I hide it? lol
My wife and I are fully capable of watching porn together from time to time. I'm not one of those married men that needs to hide things from his wife (like porn, for instance, or if some other chick were to tell me she was into a threesome). Two mature adults who truly love each other should be able to talk about anything.
Also, like your machine is for you, mine is customized to Me. Here's what the 3 most valuable things in the world are to me, in order of Most Important to Least Important. My family, My Marriage (kinda ties into the first one), and My Computer. The rest of existence is nothing when compared to those 3 things. I value all three of those things over a stranger's life. Call me F'ked up but that's just the way I am. Yes I know a person's life should be worth more than Any one Thing...yadda yadda, etc etc, cry me a bloody river. I worked hard and busted my ass for the few nice things I have in life. I value that a lot more then I would, say, a buss load of innocent children flying off a cliff. Call me an evil bastard...*shrug*
Then again, karma's a bitch, and maybe all the bad shit that's going on with my health is directly related to me being that kind of person. Who knows? I still do my share of "good deeds" and put my fair share of "good karma" out into the world. I guess it all depends on who you would ask. Some people will tell you I'm a Saint or a God-Send, other people will tell you I'm Satan made flesh and you'll stay away from me if you know what's good for you.
