Her: "I would like to do that... but should I?"
Him: "I would love to see that... but would she?"

The young lovers fantasize much about what they could be doing with each other, but only few of the fantasies are mentioned in between them, and even less become agreed upon. They fear that many of the things if brought up too soon or too quickly could have a negative effect on their relationship, but also the fear that if they wait too long then it may possibly never happen the way they want.
But someone has to be brave, to break that fear barrier through a spontaneous action, to prove "Yes, our love is more than just a respect of limits", to express "Here I am, enjoy me!"
