During the first half of season 6, in "The Parking Spot Escalation" and "The Fish Guts Displacement", Sheldon is pushed further after seeing Amy partially exposed and taking care of her while she is ill respectively. In "The Cooper/Kripke Inversion", after being directly asked by Penny if he would ever have sex with Amy, Sheldon admits to Penny and Leonard that a physical relationship with Amy is a possibility, and being touched is something he is working on. While upset about Kripke, Amy does give him a consoling hug that Sheldon seems to need, and want. Even so, Amy has offered other romantic physical contact, and was very uncomfortable when they had to cuddle. In "The Spoiler Alert Segmentation", Leonard temporarily moves out and Amy proposes that she would be his perfect roommate and tries to move in, though Sheldon is uncomfortable with this change in their relationship. While playing Dungeons & Dragons during "The Love Spell Potential", Sheldon's and Amy's characters are commanded to have sex within the game. A very upset Amy asks Sheldon if they are ever going to be intimate and he again admits that it is a possibility.
