I don't think you need worry about the 'emotional side of dance' until you have mastered the basics. You say you have been only dancing a few months so work on the steps, footwork, posture, turns and walks before worrying about anything else. Arms in latin can be very expressive but they take work not to look mechanical. Often women don't want to put the work in. Your 'inner tigress' can be released when you can dance.
