NB I'm not looking for suggestions. It's more about the process, of choosing something that meets the specific needs of the people involved.

I have a new sub, who is interested in punishments both sexual and non sexual. Obviously I intend to discuss what this means to them, and take my cue from there.

I just wanted to find out if anyone had any ways to make this a bit more engaging. Particularly I don't want to give the sub too much power. They're hardly being dominated if they're literally choosing how I treat them.

I feel it's important a punishment is of some benefit to me, as well as putting them in their place. But I'm a person of few needs! So how could I approach this differently / better?
