STOP doing this in findom. Your subs are people too. Obviously some are demanding and jerk you around but that’s really not the case with the ones you actually want to have and to keep.
If you can’t be empathetic then consider that you are unsuccessful because of this attitude.

The use and abuse is a KINK. It is SEX WORK. They are not coming to you to be immediately belittled and/or constantly degraded.
1) no consent has really been established and 2) you’re giving out free service and content.
Establish ground rules. Learn what works for them.

And STOP calling every single sub or potential sub names before any context is established, consent given, or payment received.
