Fair enough, that's a point of view I did not consider. But still, the sex one could perfectly be on a more similar scale by for example putting as Level4 something like "showing forced or violent sex", just as we have death with gore at L4 for violence). And I know we are talking about a '90s rating system but I lived that era and it's something I always thought, even back in the day. For example, 80% of the movies with guns, bullets and blood AND a sex scene never show women breasts or genitalia, not even for a split second.
