My Daddy has a different name when e is female-identified (very rare these days), does that count? I usually use "Mistress" instead of "Mommy" in those situations. (Come to think of it, that hasn't happened in about three years.)
Early in our relationship sir chose a name for me. It seemed right to him and it makes me feel treasured and special to be called by that name. If I didn't like it I know he would understand that....but I love it.
Master calls me His pet...His perfect little slave...this is enough for me...should He ever choose to give me the gift of a name simply from Him i would love it...i would never refuse Master...
Up until a year ago i didnt even have any idea that some subs were renamed. Then i had an experience between my Master (whom i've been released from since due to issues with out distance) and our Mentor.
We has a small spat over something and i went to our Mentor.
the Mentor misunderstood me and thought my problem was with my Master changing my name
Needless to say, when we all got together to discuss it, i was very confused, and my Master was too!
While that wasn't the argument we were having, i don't think i could ever disassociate myself with the name i've carried my entire life. i think the name that i have is exotic and beautiful in its own right, and what it means is very fitting of a submissive anyway. i suppose for some, though, it's a journey to be taken!
