Leo is one of the Zodiac's most affectionate signs. You love to be in love - you need to be in love. How else can you be the singular focus of another human being?
You are romantic and passionately playful and creative. You can be uninhibited and even sometimes goofy.
The thing you can't abide in a relationship is monotony (oh, and not being the center of attention). In return you demand a lot of affection and loyalty (and attention).
But take care. Sometimes you could be asking more than someone is able to provide. You will have to think about if that's enough for you...
