1. Play games. Question game is my fav, I would say its a must. Its like truth or dare, but without dares.
2. Make your conversation sexual, ask relationship related questions. As a rule of thumb avoid all interview questions, you may even tell her that you dont want an interview.
3. Talk about dreams, preferences, spirituality, lifestyles.
4. Always steer to sexual connotations. She must know that you sexually attracted to her, and she must get comfortable with this idea and comfortable with discussing sexual stuff with you.
5. Escalate verbally and physically.
6. Stay outside of a usual date frame!
