This relationship will need a fair amount of work in the long run. Initially there are lots of things you seem to have in common and you will find that attractive. You both like to be effective in your actions. You like to see things getting done instead of sitting around thinking about them. However, the motivation behind your preferences are extremely different.

You will be evenly matched as lovers. Aries has the strength and Capricorn has the stamina. You both come from signs of an animal with horns, so you are both strongly sexed. Capricorns aren't very keen on experimental sex though. You like it strong and conventional too. To an Ariean the body is more important than the mind, so their imaginations aren't put to work thinking up variations. There should be few complaints in this department from either of you.

You can make a marriage that is better than many might think. However, be prepared for the Arian's temper. You will have to try and do things on the spur of the moment for his sake if nothing else. You are both able to appreciate each other's capabilities. You are both willing to share your own in return for some of your partner's.
