I saw the game game engine was very broken some time ago, I imagine it had to do with your problem. The dev spent a lot of time fixing stuff and is already working on the next update, so probably the bugs are fixed by now.
I remember seeing a mod that gave some bonus depending on the species of your character. Like cats got more bleed damage, horses more hp and so on. I don't know if it updated
They have a lot of different stats besides the ones related to slavery, stuff like submissiveness, preferences, fear and so on. I imagine it's a combination of all them. However, the way the game is right now it feels like it's a complete random thing.
If you mean reducing the threshold from the default 3L (IMO about 500ml-800ml too high), then no. You could try giving your partners SuperShaft since larger dicks cum more. I use the hyper mod which makes Alex sell a gun to resize boobs and cocks as well as increase the chance of NPCs generating with giant members.
You can change the gender distribution and control the species that will show up, but as far as I know you can't set the average body type for now. Maybe there is a mod but I don't remember see one for that.
When you are in the main menu, go for options and look for the enable modded launcher. Restart the game and you will see the bod browser. Look for the version of the mod before installing one, the game is in 1.8 right now.
I'm not sure I understand the question, as I don't think there's a mod that stops crashes, more likely the opposite.
Depends on the implementation. But seeing that the dev themselves agreed to add it, It makes sense for it to be good enough to be implemented without issues.
