I get that, absolutely. Childhood trauma sessions take a lot of of a dom, everyone in fact. Not everyone is going to want to go there. For me it's very rewarding when the sessions evolve from my being the abuser to recognizing that I am with them and supporting them through their trauma. I find the times when the sub changes from thinking he deserves degradation to when he realizes it's something he can enjoy separate from his vanilla self very satisfying. Yes, it is a lot of work. Luckily I have a nice mix of clients and can enjoy regular old kink.

Race play, and any other deep degradation, without this context would be a limit for me.
