One of the things my parents taught me when I was young was that anything you saw was in your mind forever. This phrase was always part of a moral lesson since the idea behind it, at least as they (and their incredibly conversative religious beliefs) intended it, was that sin and temptation was best avoided entirely because once it had gotten into you, you couldn’t entirely get it out. The only way to stay entirely free of those things was to avoid them entirely. It was a core aspect of why I wasn’t allowed to watch a lot of TV shows on public broadcast television (even one glimpse of a swimsuit or bra, or even two people making out was enough to get it banned in our household the entire time I lived there), why I was only allowed to play video games that didn’t include Suggestive Themes (even though they were apparently just fine and dandy with violence of any kind), and of my complete failure of even an abstinence-only sex education (the perks of being home schooled is that your parents get to fail three times at teaching you about the birds and the bees, call it a complete education, tell you to Just Say No to touching women who aren’t related to you, and then never speak about it again). It even came up a bunch when I finally escaped the isolation of my home schooling and started asking questions about things I didn’t understand in high school. Better to avoid something entirely than to encounter it at all, since that’s how the devil slowly worked sin and evil into your once-pure mind (all of which is a pretty big contradiction of the orthodoxy behind the sacrament of confession in Catholicism).
