Ha, my parents are horrible with computers; however, I don't like to look at porn because of all the neagtive things about it (there are tons so I wont say them all). Sometimes I just can't help myself however, and I look at it. I can stop whenever I want (I'm no addict, mine you) its just easier and more pleasureable for me to have visual stimulation (though normally my imagination is good enough
So yeah... don't look at it if you can. And DEFINITELY erase your history!
