Question: Are there different types of slavery?

Answer: In my slavery I/we have to obey the Master that has access to slave Aureus, which usually means that Master bullwhipped us to a point where he could get his command structure recognised. I /we recognise other Masters & Guest Masters at their various levels some of which have bullwhipped to a controlled point within the Owner Masters boundaries and some other Masters are respected & served even though they have not bullwhipped but are respected by us [Aureus/slave Aureus]

Though I/we respect all Males, does not mean we have to serve or be a slave to all comers.
A non-consensual slave in captivity will have a Master that owns her and may not want all to command her.

Its a bit like your car which is your slave to transportation & I know many that will not share their cars let alone their slaves.
