An idea to consider in the future, would be to add dynamic objects that are able to interact with the characters in the interactions.

For example, condoms, which could be found in RDL (in the rooms) and you could put them on the character's penis, even, with a physics system and fill them with cum, so that they look like a balloon when the character pulls his reproductive member out of any hole ;)

Another example is the fleshlights, and the possibility of being able to use them to make the character penetrate them with the coupling.

This would save people from having to create models with the character base or make them more compatible, and just create models directly for this purpose, also adding another section in the cloud, where one can upload their own interactive objects, making recreations of bad dragon dildos, or even a sex machine.
