What are the master's options regarding the marriage of a male slave who requests marriage?

Primary text

If the obligation to arrange marriage for the male slave is established, the master has the choice between two options: either marrying the slave or granting him ownership of a female slave whom he can take as a consort. Furthermore, the master may marry his own female slave to the male slave because the marriage of a female slave to a male slave is permissible without any prerequisite condition for the male slave. The master is only obligated to arrange the marriage upon the slave's explicit request because matters concerning marriage vary among people in terms of necessity, and the need is only known through the slave's request.
