What is the force of love or sexual attraction called?

I'm sure that there will be others to give you a overly technical answer that you will have to research just to understand, but I'm going to attempt to do what I wish more people did when discussing deep topics... KEEP IT SIMPLE.. If I could make a triangular chart, I would place Love on the bottom-left, Lust on the bottom-right, and Romance at the top. Surprisingly, lust is the passion for what you can't or shouldn't have, while romance is the passion for who you love. But more shocking than this, love is not the passion for anyone, it is actually a decision to prove your desires and passions with action.

So the force of love or sexual attraction might seem similar, but they are completely different. But if I were to give it a single Word, between Romance, Love or Lust, I would choose Romance.
