How do you choose what you wish to own, approach them,, and let them know that from now on they are to be yours? How do you keep them afterwards? Making sure that as much as you know, there wish for no escape.
Personally I go by looking for what it is that they truly seek, or show them something and make them believe that it is so, and only I can provide it.
I usually go with demonstrating I'm superior to them in some way (ex: making wittier comebacks than them, picking more girls than them etc) and things kind of click in that superiority / frame. I got straight guys to give me blowjobs / do stuff with me by throwing their inferiority on their face and following with agressive advances, works well
Like most plantation owners, every other month I head down to the auction block and pick out the strongest man I can afford and bid on them. I find good heavy chains help me keep them around but the cleverer and truly driven among them manage to slip away from time to time, but most of the time we can track them down with the dogs.
