Both share a similar approach to sex (they make the most of every opportunity). Add to this a mutual love of the outdoors and a fondness for socializing, and you can see why they get along. They're also intellectually well suited: Both have a wide range of interests and love to talk about them. Sagittarius is more philosophical about problems than Aries, who becomes more personally involved. The one question mark is their combustible temper. Arguments are heated but short-lived -and the making up will be fun. A perfect match.
