(“to be the object of anal penetration is a crime in the freeborn, a necessity for a slave, a duty for a freedman”).110 What is significant here is that sexual subservience is considered the “duty” only of the freedman. It is not considered the “duty” of a slave. This is because, again, slavery was not a moral relation. The master could do what he liked, and there was nothing the slave could do about it.
