Capricorns are very comfortable with each other, but that comfort can be a bit dull from time to time. When both partners are guarded, it's difficult for either of them to really let loose. Capricorns complement each other physically, but may be missing fireworks unless they take the time to let their guard down. Capricorns should be careful not to let their reserve and detachment drag their relationship down. Lighten up Capricorns and smile!
