Hi Scorpe
Well done on first doing research. A power exchange dynamic can be such a mind-blowing relationship to have, especially when both are open to making the others' fantasies come true.
I can't even begin to answer all Your questions and i won't try.
I will simply caution that Your foundation and relationship with her must be strong and open. Communication must flow openly and freely before you both embark.
My experience is that people underestimate the amount of communication that is needed to add another party to a dynamic.
It isn't ONE added dynamic; it actually adds several layers:
(You with the man. Her with the man. Her and you with the man. The man and you with her. The man and her with you)
Learning obedience is something else I want to comment on, please.
Jealousy is a sign of insecurity, not disobedience. That insecurity can be over something real or imagined. Jealousy can break things apart or actually tighten the ties that bind.
I'll be keeping an interested eye on other responses and wish You and Yours all the best.
