In more detail, once a monster has accepted a man as her husband her body adapts in such a way in order to get the most pleasure possible from him that she actually becomes unable to experience sexual pleasure from another man. More than that, the essence/mana of other men becomes unpalatable, even disgusting to them. Not that a monster would want to cheat regardless, but these are some strong motivations that make it essentially impossible.

The settings outright notes that even if a man was able to rape a married monster, she would feel nothing (and doubtless would get revenge as soon as possible), and also since a monster's body cannot be broken by sex, the rapist wouldn't even be able to hurt her via it.
