Unmarried monster girls generally won't attack men who are already married. its stated in MGE1.

Also, perhaps for the same reason, they tend not to attack men who are strongly stained with the odor and demonic energy of another monster. However for some races, it's fundamentally accepted that a man will have many wives, and he'll just keep having sex with the many monsters who love him one after another, or perhaps keep going with several at once.
