Basically can Steele have an option for tentacles? Either from Goo Biomass like Celise or having multiple taildicks like Tavira. Is it hard to code in?
Currently you can have tentacle dicks (with no extra functionality, as far as i can tell) from using Galomax. Also you can have a cocktail, which is basically a tentacle as well. There are currently no scenes in game which require or reference you have tentacles though (as far as I know), unlike in CoC.
If your dick has the Prehensile flag, you get some extra blurbs regarding it throughout the game. Nothing major, and definitely no unique sex scenes. You can get the Prehensile flag regardless of what type your dick is; Equine, Tentacle, Human, etc.
