@CheshireHuman - I dig it. It sparks ideas for improvement. I have an idea for soft working muscles for realistic movement that was inspired by those segments. That's still on the drawing board, but one of these days when I have a bit of cash to burn for the prototyping process, I'll proceed with development.
Another idea while listening: Can a TPE vagina be paired with a silicone doll? 🤔 It could be the best of both worlds.
