Followup on this:
I've now completed fixing this up and making a more user-friendly prefab and exported it to be a .unitypackage. Please be aware that the only person I can supply this to is the creator(Rain Jur). I will not distribute this to anyone else myself!
That being said, if you (Rain Jur) want this package, let us find a way to connect and I'll send you the file.

Changes:
- Edited a bunch of animations to remove missing components
- Updated Parent Constraints to VRC Parent Constraints
- Automated "Parent Constraint" Objects Armature placement with Armature link (VRCF)
- Fixed Animation Paths (VRCF)
- Moved from Bools/Position to 1 Int for all positions per Portal
- WD On for all States
- Updated State Logics to simplify the Layers
- Renamed layers to "Lovegate: STATENAME" and minorly adjusted naming to try and make their purpose more clear
- Added new layer to simplifying adding Avatars mouth open animation
- Added References + Example Penetrator (Lollipop from Wholesome)
- References Delete on Upload / During Play Mode
- Streamlined Scaling (Portal and Penetrator Parents now all on scaling 1. Scale Constraints for the References point to "Handle Portal" and "Penis" Objects
- Cleaned up unused files
- Renamed "Drag and Drop onto Avi Base" to "Lovegate"
- Moved "Full Controller" and "Toggle" from "Exit World Constraints [Avatar Root"] to "Lovegate" (root object of prefab).
- Updated Parameters and Menus
I am unsure if at this point I am missing one of my changes, but that's the important ones that come to mind.
