Hmmmm... interesting thoughts.
Even defining those words opens a can of worms. :-)
What has been defined as a slavemissive, many would call a slave or sub.
Call yourself what you want and thrive in your relationship.
As for me, I prefer the term "pet".
I'm so not submissive, yet I'm not the domme in my relationship with my husband.
And because my husband takes charge when we play, many would call my part
the submissive or bottom.
I'm more a wild creature, like a tigress, that's tame only for him, because I choose to be, not because he "tamed" me.
While my sweet Nat, can play the role of sub, he's really more a pet, too.
