Uh. I could check in the back of my parents' closet (hidden under some fabric) for at least a decade's worth of dirty magazines. It's true that that's less than a lifetime's worth of pictures and articles, but I'd say that that's effectively equivalent.

The only thing that's unhealthy is not being able to talk frankly and honestly about sex and sexuality with your peers, parents, and other important adults in your life. Well, that and never being told that sex leads to pregnancy, or how to recognize common STDs... but you're likely to get that "for free" if you're able to talk frankly and honestly about sex and sexuality.
