How did Sheldon has such an extensive knowledge that he dreamt of a sex dungeon replacing his former bedroom?
•Kripke asked if they were using toys.
•He finally read the book his friends gave him.
•Penny's battery-operated dog toy seemed highly unusual and suspicious.
•Finally, the in-depth research he made about everything related to sexual nature before his and Amy's big night.
A/N: I don't know what I'm going on for on this one. This is just what I thought the most acceptable reason he knew of a sex dungeon. Sheldon is not ignorant. He's just not interested. If found a story with similar plot or based a story from this prompt— I'm shamyshenanigan on IG! I'd love to read the story.
