The Blue Star Continent and Earth were two vastly different worlds, so one should not look at things from them with the same logic. Steve had been slowly adapting to this mindset.
For instance, the Earth had only one moon, while the Blue Star Continent had four moons. According to the logic of Earth, one would be considered mad if he or she was to say that there were four moons. But, that was logic considered as being perfectly normal in the Blue Star Continent.
Another example of this rule was when Steve heard his two women talking about whether they should let Steve find more women to share their pleasure. This would be impossible on Earth, but on the Blue Star Continent, the strong have the privilege of having more than one woman, as it is seen as a symbol of strength.
As Steve still thought like an earthling, he immediately dismissed this idea. Although the Blue Star Continent allowed one to have more than one partner, Steve was not that promiscuous.
