(here is a excerpt from the ecology page..the monsters that become prisoners sub title)  Monsters can sense when a man is strongly stained with “mamono mana” or a monster's scent, and they can tell that that man is a “monster's husband” and whose husband he is. Among monsters, there is an implicit understanding that when a human man is already another monster's husband, he belongs to that monster, and they shouldn't assault him at random, so men who have become a monster's husband basically don't get assaulted by monsters. However, in the case that the monster really feels strongly about the man, or in the case of races that are fundamentally polygamous, that's not necessarily true.

If a monster feels so strongly about a man that her instinct has recognized the man as her “husband”, and she's already begun to change into a female exclusively for him, then there's no way she’s going to be able to ignore her intense desire merely because of something like an implicit understanding. She'll give in to the urge, assault the man, and fuck him. After that, the monsters who share a “husband” will end up living together, cooperating at times to milk mana from the man, and at other times, fighting over who gets to have sex with him longer and more often. Once this happens to a man, he'll have to catch all the desire of multiple lascivious monsters with his one body. He'll end up having to keep offering them large amounts of mana, every day switching off, or ,perhaps, doing all of them at the same time.

(basicly this answers youre question in full.....mamono have a vague/implisit rule of not attacking men that are already someones husband but if they deeply love and desire him to the point hes technically already her husband then shell ignore that and go for her dtronger desire to be with the one she loves and have his kids
