He's ruled by the red planet Mars, so you know this guy is hot. But he's also cold. He's a man of extremes, whose loyalty is to himself first, and his solo journey. On that note, the Aries man is so absorbed in the moment that he may not notice you at first. He's got his eyes on the next prize. This makes it easier to observe him from afar, and develop a huge crush.
(When his gaze finally does beam on you, don't wilt and play shy or too smitten. He doesn't want a done deal. That's an instant turn-off to such a forceful and confident man. He's looking for tension in romance, the thrill of the hunt, with the goodies kept at a tantalizing distance until the right moment. In old-school lingo, it's called playing hard to get.
The Aries Man is full steam ahead, and gains momentum as the night goes on. You gotta have energy to spare to keep up. It's tempting to go along for the ride, since his energy has an animating effect. But it's wise to retain your own sense of rhythm in the relationship, what feels balanced for you. He's thrilling, but self-centered, and you should let that rub off on you, in a healthy way. He'll respect you for it, and come back for more.
And that's the tricky part, dealing with that super-sized ego. He doesn't want a pushover, but does need a fair amount of ego stroking. He's bright, and will respond to direct, daring communications. When he struts and swaggers around the room, let him know he's met his feisty, haughty, quick-witted match.
Facing fears and moving toward your own dreams will impress him the most. As will standing up to him when he's an arrogant arse. A relationship that is fresh and full of new revelations keeps him by your side. In the end, the best path is to be your most dynamic self, and let the chips fall where they may.
