Guidance

I think it's just common sense. Many submissives want that comforting, safe space in which to play with a partner. If that partner does not have the knowledge or the skills necessary to play safe, sane, and consensually, the submissive will have doubts. Doubting and slightly fearful that your partner may maim you, though not on purpose, is not the desired head space.

D/s is like a dance, the Dominant leads and the submissive follows, but both are willing participants and active in the dance. If a "Master gives out expectations.. and doesn't consider the subs wants or needs" that's like dancing alone, or being left on the sidelines. Both partners need to be active in negotiations no matter what situation they are in.

I totally agree with tart. It's comforting to have someone with experience to make the play feel safer.

I would love to either be with someone who has a lot of experience or who is willing to learn with me. My current partner learned about BDSM and grew into the community and his role as a dom/top alongside me, which was very enjoyable for both of us. I never felt unsafe just because we were both learning.
