Failure is Learning and Fun

Sometimes we fantasize and buy new stuff or try new things and it does not work. What about other people? My wife and I fantasize about a couple thinking about trying a complex sex move or trying out a new toy. When they try, it doesn't work. It's awkward. They are trying to be serious but nothing is working. Rather than be frustrated about it, they just laugh. It turns them on. They start kissing and end up having great sex, and a great laugh afterwards.
