While Eugine's comment could benefit from some clarification and refinement, I think you're wrong to dismiss it as worthless. The status (or whatever similar term you want to use) assigned to enjoyment of sex versus enjoyment of punishment is definitely a culture-specific thing. (I can easily imagine a culture that, unlike ours, extols sexual asceticism along with righteous cruelty, and some historical examples aren't too far off.) This certainly influences the choice of values that people would like to see perpetuated.
