Thanks for all your kind replies. The fact of the matter is that I am an experienced sub, and have had a number of "master", or "owners" or whichever name you prefer.
The problems arise when the relationship ends, it is not like finding a new regular partner or boyfriend. It takes so long to "sound out" a new persons tastes and limits.
Each of my arrangements with a dominant male have eventually broken down, usually because, (a) he boringly keeps to the same scenario, never moving it on so it becomes a predictable role-play.
Or (b), he moves on without my agreement and tries to involve me in too bizarre scenes, often with outsiders or not protecting my privacy.
