Chyeah, she knows.
Apart from jokingly referring to my interests as "cute" ('cause frankly, in comparison to what goes on in her head my fantasies are as innocent as rainbows and kittens), she does not care: We're partners, not each other's thought police. And to be honest, I wouldn't have it any other way, because love has its limits; freedom of thought is the foremost of them.
No, I don't have any books, because that would entail paying for porn. Also, less comfort than your basic slide-show app.
On the computer, I don't hide it, since I don't need to. But to be blunt, all those myriads of denizens going to great lengths to make """invisible""" folders make me wonder if lusrmgr.msc and adduser are crying in the corner, slowly gathering dust. Those would be my tools of choice to "hide" things if I ever needed to.
lol wouldn't it be fun to watch hentai while having sex?
Then it's like your having sex with the anime character
???
Not sure about you, but I'd be too preoccupied to pay much attention to what goes on on-screen.
Ever tried making out in front of a running TV?
Catch much of those evening news?
Didn't think so.
