That doesn't mean that they don't take women against their will.  After all it is more of a challenge when it is a battle.  In one of my campaigns I set up a minotaur empire that the only minotaurs were male due to a curse and they had to use women from other species to reproduce, but they were a matriarchal society.  One of the more complex xultures I put together. 
  
The Mandalorians are similar, minus the matriarchal content.
