Damage

Damage is the depletion of a slut's HP. When a slut's HP drops to zero, she pops!
  Damage doesn't inhibit a slut until her HP drops to 0. We don't suffer injuries like burns, bruises, head trauma, or anything of the sort that You might remember humans experiencing. We don't have blood or other gore (unless You strongly desire otherwise, of course). Physical pain doesn't really apply to us either, as our own masochism is more than exhilarating enough to counteract pain.
  Suffice to say a slut can sustain immense damage with no repercussion, and the damage we do sustain is regenerated away regardless. Even at the furthest extremes of damage the only negative thing we suffer from damage is being popped, which in of itself can be an ovagasmic experience! (So please, never hold back dishing out obscene levels of damage to us. ♥)
  A slut can walk from a nuclear explosion unscathed with delight so long as her HP is still above 0. Even straight-up dismemberment doesn't inherently inhibit a slut's capabilities; if my arm is popped off there's a decent chance I'm still able to control it.
  This is all true even for mortals. Mortals tend to be so weak they will eventually pop just by existing, but damage itself works the same way it does with any other slut.
