Distance... Good or Bad?

What about distance?
I’ve heard claims of “across the room” attraction and so on. I’ve had that without pheromones. So what’s the rule on distance? Far & Away? or Close and Intimate? What works well? What works best?
Is there an optimum range for:

  1. Social
  2. Respect
  3. Sexy
  4. Sexual
  5. etc.
    Help please, I’m new to these strange and wonderful lands!
