Every Person is different. Sounds as if this pain slut is speaking for Everone? Or trying to. And "lecturing" You? ummm
What takes a Submissive to Subspace imo/e depends on them and Their Dominant, not General opinion.
Perhaps this pain slut You speak of can *only* get to Subspace through extreme pain? Doesn't mean All Submissives/Slaves *only* get there that way.
Me for example; A good hand spanking on my bottom will bring me up on the short end of that Leash and to Subspace very well Thank You. Hand Spanking is not heavy pain generally <G>. Or maybe I'm just too easy? lol
