My twin brother just said he doesn't want a harem, but thats because he's still Vladimir. Once he starts to understand that his whole Vladimir persona is the result of his enslaved relationships and starts to be Detsu again he will start to see things differently but that is something he has to go through himself.
Each of my brothers regardless of their rank has a different set of tastes, same with Gramps and my husband and Dad and my sons, though most of them have not distinguished themselves from each other yet and they prefer to share a slave girl.
As women we like to have people of nearly every type around us and our challenge is to think of ways to include them while meeting the needs and demands of the various men we have to think about. Here is where it can get tricky though, because while I am to think about every man whose women are present, some of those women cant think of all the men their husband has to deal with, which is why we need to have our structure of interaction so we can share relevant information in a way that each of us can assimilate on our own level.
I used to think everyone should be equal but fairly recently I have realized how boring that would be, and how mean, because not everyone wants what everyone else has and even when they do sometimes the best solution is not fulfillment of every desire.
*while the rank of the men is reflected in the harem it is not without a considerable refraction as any type of woman they might be interested in will be kept there and a low ranked slave is still a low ranked slave even if she was brought in by the emperor, she will be known as the emperor's low ranked slave and treated like a low ranked slave who is sometimes called by the emperor and while other low ranked slaves might have to do other kinds of things she will have to do some of the things that the emperor likes in all women, though this particular emperor is minimal in that sort of taste and has individual instructions for nearly everybody. It is also conceivable that some of my half brothers or subordinate Detsu brothers might have women of free rank, though they would be supported by what is within their husband's means*
**while whatever our men dream up we will do our best to accommodate it there is the possibility that they might not be able to adequately explain some of their ideas to us, that could cause strife, confusion, amusement whatever depending on what they told us they wanted, and they also understand that we react to what they say to us so if they tell us something impossible maybe they did it on purpose**
