Leo and Sagittarius are both fire signs that blend into a wonderful, magnetic, fiery, dynamic, exciting relationship. They have a great deal in common.
Fire in astrology stands for a certain magnetism and dynamism, a sense of adventure. And, certainly, it stands for passion. And they both share this, a little differently.
Leo's passion, to begin with, is for itself. Leo needs to feel that he or she is leading a life that is larger than life. Leo loves attention, loves the social life, loves the good life.
Sagittarius has a great deal of passion, but its passion is also, in addition, of course, to sexuality, its passion is for adventure, for getting out into the world and not being tied down.
They can blend their energies very well, because each of them allows the other, unlike to, let's say, a couple in which on tends to want to control the other, Leo doesn't necessarily want to control the Sag, and Sagittarius doesn't control the Leo. What happens is that that fire for life finds its way into a life that they can build for themselves, where they create a certain dynamic life style.
They can use their creativity, and both of them have sparkling social charm. Both of them are interested in doing, and experiencing new things, because each of them wants to live a life. Leo wants a magnificent life, and Sagittarius wants an adventurous life, and so they can blend that kind of magnificent adventure together.
So this makes a very good love affair, and even better marriage.
