I have friends that prefer some parts over others... Even T prefers one part over the others... but T says she doesn't work with parts... too bad it is a part she is talking to!!!! Even my pets and kid prefer specific parts over others.
OT but... there are some parts that my horse will not let ride her or even come near her!
Honestly I think massage T is the first person in our life to love us all the same and not care about who comes to see her. Although she is always very encouraging of the shy/really hurt parts to come out.
I am OK with it as long as all the parts stick to our internal agreement about acceptable behaviors.
I have a 'friend' right now who is very upset because my "slutty part" as he calls her is no longer allowed out around him because she cannot honor the guidelines we have agreed to internally (consensus not unanimous... LOL us unanimous on anything!)... and he uses her to get past boundaries I have set with him.
