Adding new characters/monster/animals

[Gorillaaaa]

Hi!
I want to make new characters, animals, monster and animate them. + Sex animations. Is someone can tell me if this is possible? Without using someones else skeleton.
For example Character (race) i want them a bit taller/fatter, i hope it wont be a issue, same with monsters/animals. I would like the fact they have own set of animations, so they wont collide with older ones (during sex scane they probably wont fit exactly because of changes in character proportions)
I was looking everywhere and i couldn't find answer. If yes, can someone give me some guides tips how can i do that or explain how it works.
I would be really appreciate any help because i want make a really good detailed sex scenes and record it.

I'm trying to figure it out what would be the best solution for it because like i said earier, it would be nice if every character/animal/monster has own set of animations, and i see only 2 solutions if i understand this well. 1. This idea above or 2. Edit skeleton but just make animations for every proportions for example ,,TallerArgonianFFemalePoseX", ,,Fatter ArgonianFFemalePoseX" do i make sens or i talking like stupid?
