Editing Monster Girls/Extra (section)

===Regarding general monster girl biology===

* Egg-laying monsters don't mind others eating their eggs, provided they are unfertilized of course. It is easy to tell fertilized eggs apart from unfertilized ones as the latter are notably smaller. (source: Kenkou’s Japanese Q and A).

* Monster girls may get the equivalent of periods, but they are unlike human ones. There is no bleeding or pain, rather they become more sensitive sexually. (source: Kenkou’s Japanese Q and A).

* While monster girls have preferred diets, they are all in essence half-human thanks to the Mamono Lord. Due to this they can eat whatever a human can eat, even if it would be poisonous to the animal they have a similarity to. (source: Kenkou’s Japanese Q and A).

* Beastmen types in general were among the monsters known to have in rare cases overcome their human-killing instincts and fallen in love with humans in the age of the former mamono lords. (source: Kenkou’s Japanese Q and A).

* While its not that unusual for a monster girl's home to be reinforced/sturdy, it's not something the average home has either. Monsters are only overwhelmingly strong at "maximum output", and are good enough at controlling their strength that even a wurm is unlikely to accidentally break a door by knocking on it and such. (source: Patreon PM from Kenkou).

* Undead being able to reproduce applies to those with entirely spiritual bodies as well, like phantoms and will-o-wisps, since they are a "race" rather than just a spirit. (source: Patreon PM from Kenkou).

* Incubation time for monsters that lay eggs varies depending on the monster species, but is no longer than a month. Egg care involves one of the pair warming the eggs regularly, and keeping the bedroom the eggs are kept in supplied with dense mana from their parents having sex. (source: Patreon Q and A).

* When monsters become able to birth incubi, the ratio of male/female births will mostly be 50/50. Exceptions will be species which are natural harem-builders such as devil bugs and khepri, wherein many more girls will be born than boys. Echidnas will also be an exception, as the first child is always an echidna, and as mothers of monsters, monster girl births will predominate (their family structure will often be many big sisters and one little brother). (source: Patreon Q and A).

* Tsukumogami monsters can be born anywhere in the world. However, they are more likely to be born in Zipangu, perhaps due to special differences in the air and mana there. (source: Kenkou's 2015 Ask.fm page).

* As a fantasy RPG setting, it is fair to say that melee weapons and magic in the MGE are far superior to real world firearms. To an MGE monster, a weapon that merely shoots metal balls is nothing more than a pea shooter, such is the nature of their durable bodies. Unless the shooter can infuse their bullets with magic, they wouldn't stand a chance using guns to fight monsters. (source: Personal communication with Kenkou Cross).

* When monsters become able to birth incubi, they will be born in the conventional mammalian way regardless of what type of monster their mother is. This is possible because of the humanoid forms monsters have. They either have a structure like a human womb already or will be able to create one in their body for the baby. (source: Patreon reply).

* Monster girls also have hymens. There's some individual variation—some of them bleed, and some don't—but overall, there's a tendency for them not to bleed much. It seems that demon blood tends to be a deep reddish-purple color.<ref>https://twitter.com/k_cross/status/1492409672644513796 </ref>
