Sagittarius is a sign that loves to wander. From your prodigious travels to the exploring you do in your own neighborhoods, chances are you have a completely different experience than other signs.
You make friends, and find all the cool, secret places no one else knows about. In relationships, you need freedom to roam as well.
Though you're capable of committing to someone and being loyal and devoted to them, you need to feel that you can move around, or even have adventures together.
Being with a Sagittarius means you need to leave room for exploration - of love and affection, intimacy, and ideas of all kinds.
