I do worry about My slave if I were no longer able to dominate him due to circumstances/other reasons... but this is part of it unfortunately. Things end, not just Ds rels but normal rels/friendships, things and times move on. I have no plans to get rid of my slave at present, as long as he keeps behaving!
There are infinitely more slaves seeking a Mistress than Mistresses seeking slaves, putting us in the position where we are able to pick and choose, and the subs are kept pathetic and desperate, as it should be. I have never had to look for a slave, other than my profile being on various fetish sites etc.
There is the fun novel element to the domination [the housework/gifts etc] but the subs submit because they need the creativity of a dominant Woman who is able to mentally manipulate them as well as just telling them to do tasks... it is about the tension, the psychology, understanding how the male submissive mind works and using this to your advantage. I would advise doing extensive background research and study so you really get a 'feel' for FemDom .. and you are aware of the full range of techniques not just tangible and physical but also mental/psychological.
There is more to the art of FemDom than at first meets the eye!
You end up in complete control of another person, you need to be responsible. SSC and RACK are two ways within the scene.
SSC: Safe Sane and Consensual
RACK: Risk Aware Consensual Kink
These are BDSM codes of conduct if you wish, they are there to physically and mentally safeguard both Dom/me and sub. I always comply with a subs set limits and stop at any mention of their safeword. I use the 'traffic light' system too, I can check he is ok by asking 'Green?' and he is able to stop the scene for a check up and discussion if he says 'amber' or stop entirely if he says 'red'.
I don't see this as hard work but more something innately natural, if it is hard work and you get tired/bored with it then in all likelihood either Domination isn't for you or that sub isn't for you!
The novel techniques and ways of making them submit, chastity, orgasm control, cuckoldry, cbt, forced fem, sissification, forced bi, corporal punishment etc etc are just ways to express how I already act naturally, like I own them, I am superior due to my Femininity and they are submissive because they are male.
I'm a Dominant type of person in everyday life so I guess it was inevitable that I would find an outlet for this in some satiating way, FemDom/BDSM is a safe and creative way to express what is already there inside me.
