Not unless you have the expectation of getting your way... or unless you think you'll get what you "really" want.

But if being bratty and put in your place, in whatever manner your dominant chooses, and that your dominant does so as they please, it's just another form of D/s play. As valid as dom/sub, daddy/princess, headmaster/student, doctor/patient.

But make no mistake that if your dominant isn't wholeheartedly into it, if you can't adjust when he/she want to change it up, you will lose him/her.

And all that said, I don't think the brat dynamic really works online. Brats need hands on attention imo.

Me? I prefer adoration and obedience.
