I have dated Gemini's and enjoyed some of the best short-term relationships in my dating career. In the beginning, Cappies are attracted to the Gemini because they are exciting adventurous and love to have fun. This is refreshing to the Capricorn who rarely plays outside of the rules. In the beginning, the relationship is fun and the sex is fantastic. The Cap is also attractive to the caring nature of the Gemini but eventually, the unpredictability of the Gemini will clash with the Cap that needs structure and stability. Also, the Cap will eventually appear boring to the Gemini once the Cap becomes wary of running with the Gemini and began to settle in their familiar ways. Cappies are called "old goats" for a reason. Now, can they work? I feel if they're mature they have a better chance as they settle and crave security. If they're younger then it will take work but anything is possible if the love is true.
