When they first leaked what would happen last night, I was apprehensive because I couldn't imagine Sheldon getting over his aversion to it since he is so stubborn. However, then I started thinking about how much he has grown over the years that he's been with Amy, and also through being friends with Penny and Bernadette, too. I'm happy for Shamy, and I hope this brings them closer together and he starts to respect her needs even more.
