Mars rules the signs of both Aries and Scorpio, which is probably what provides them with the intense sexual chemistry that other couples envy. If used correctly, the differences between these two can really complement each other. For example, Aries can really liven things up for Scorpio with their sense of adventure, while Scorpio can provide a relaxing influence that helps to calm the notorious Aries temper.
There's a lot that could go wrong with this high-energy match. Firstly, both should make sure that there is substance behind all of the sexual attraction. But perhaps their biggest weakness as a couple is stubbornness on both sides and an inability to admit when they're wrong. The fights can be crazy between this couple, but if they both learn to compromise they could really end up going the distance.
