Well ...
Sorry, amigos. My lovely wife scoped my page history (which I foolishly forgot to erase...), and found my figgling of our love, Milena Velba. She seems to be very jealous of her. She doesn't mind anyone else! Now she wants to get implants to make me happy. I personally can NOT stand imposter tiggles. Her natural 34-I cup is SECOND best to ME! Anyhoo, she changed my PC password and everything, just after deleting every Milena photo and video I had. It took me years to concoct all that delicious filth... Gentleman, I wallow in sadness.
Well, you had several options.
One, use another user (switch user) or at least profile (if using Firefox), including hiding the profile (modifying a key ini file) and only enabling it when you are on.
Another is to locate the profile on an encrypted drive/filesystem, so it is not accessible unless you mount it.
And there are many other variations on those themes too.
Lastly,
You Might want to consider being honest with your wife first next time. That always works very well in the long-run, especially if you're up-front. Not trying to lecture, just saying, if you like porn, let your woman know that.
There's nothing wrong with liking anything, as long as you find a partner that is compatible with it. Values are not absolute, although values are shared.
