Sounds like it's another rumor - like in Season 4, The Herb Garden Germination - where he and Amy spread a tale that they had sex to see how it travels thru the gossip vine of their social group. After all - in that episode, Sheldon told Amy that pretending to have sex with her gave him "a great deal of satisfaction."
