bboyneko: yes, the filenames and the labels can be misleading. The point is, anybody with a healthy attitude toward sex will develop their own self-censorship as to what's appropriate and what's disgusting/illegal.
One doesn't have to resort to Watchtower-esque censorship and control tactics when discussing sexual aspects with their kids. If the kids are old enough to understand these things, they have to be encouraged to self-discipline, rather than learning how to circumvent parental rules.
What's repressed unnaturally now will spring back ten-fold later in terms of negative consequences.
