A lot of people have issues with display of affection in public, definetly something to talk about. Why not ask her what she wants and expects from you and then be intimate in those ways?

My Demon revokes any prayer
He's grown contempt for love and hope
He betrays trust, twists truth and fair
Indifference is his way to cope
Engulfing sound of sensations
He quells with voices of despair
And muse of short lived inspirations
Flees at the sight of his cold stare
~Moy Demon - Mihayeel Lermontov~
