i tell them you are inexperienced until you feel like you got you figured it out mostly. even though i have experience, sometimes my expectations are different than what the customer is expecting and it may not mesh. before i agree to findom sessions, i need them to tell me what their spending limit (if they have one) and establish boundaries on both ends.
if they start crossing anything established without discussing or showing me problematic behavior, i will warn or ban them. like sending me pictures of their negative balance crying that they have no money to give me for example.
