Big hugs! My thoughts are that within the lifestyle terms are as individual as relationshipsFrom the moment we met, my Sir chose to call me by the term "pet" He on the other hand does not choose for me to call Him Master, but prefers Sir or Sarge. I am most definitely submissive, but i melt at the sound to this day of "pet" from His lips....and we are together over 18 months. *Smiles* so i totally relate to the warm feeling you get from the term. What ultimately matters and should hold the only power over the relationship is how the people involved feel, choose and relate too...it sounds as though you have stepped into the beginning of a wonderful journey!
big hugs!
