About the Dom/Sub Universe The Dom/Sub Universe is a fictional setting where humans possess a "second gender" in addition to their biological sex. They are mainly classified into Dom, Sub, and Switch. Basic Natures Dom (Dominant) Individuals with a nature to lead and direct others. They gain satisfaction by giving Commands to Subs. They are not necessarily aggressive in personality. Sub (Submissive) Individuals with a nature to accept directions and influence from others. They gain a sense of security and satisfaction from a Dom's Commands. They are not necessarily quiet or timid in personality. Switch Individuals who possess both Dom and Sub natures. Their role changes depending on the partner or situation. Normal Individuals who do not possess Dom or Sub natures. Command Special orders issued by a Dom to a Sub.
