This union can be one of those where everything is either divine or simply disastrous. Unfortunately the probability is greater of the scales pointing in the latter direction. The issue concerns the fact that Leo and Taurus both are are "whole" personalities with a focus on integrity. They are self-centered and usually self confident, although both have egos that at times seem considerably shaken and fragile. Imagine two steaming, steady trains whose trails cross each other at a 90 degree angle, and you have Leo and Taurus. They are probably attracted to each other, they appreciate the fact that they can be lazy in each other's company, and as for their sensuality and passion - it finds all the response it needs in the partner.
But, but, but, but...the success of this interaction is highly dependent on each partner's ability to resist several of their natural inclinations. Exaggerated demands, stubbornness and jealousy are typical such qualities. It also seems that Leo and Taurus are destined to argue about values and life-style. Leo, stubborn to a fault, usually want to flame through business in one sitting and then forget. Taurus is not happy with that, since every principle needs proper consideration and time, and chances are Taurus feels that Leo is a little smug and too often gets his or her way. I am sure this combination has potential if at least one of the involved shows important other, more flexible horoscope influences. Otherwise, It's a neckbreaker. Too much pride and minds too narrow.
Taurus and Pisces are similar in many respects, except when it comes to priorities and what they deem to be important: in sum, their respective world-view and sense of reality. Taurus, while not a complete stranger to romanticism, will still always mind the basic needs and practicalities over ideals and intuitive hints about what might work. They are also the most physical of the signs, and consider lovemaking to be a simple, lustful and straightforward kind of operation. With Pisces it is not so. Their world-view tends toward the mysterious, and they often feel as if their gut hunch about something is more important than the bare realities of a situation. Likewise, according to Pisces the sexual act is not benefited by a routine, consistent procedure. There has to be magic and fantasy, the allure of dream-scenarios that stimulate Piscean fondness for the unusual. It is also likely that Pisces won't have the stamina and inexhaustibility to match the slow, steady Taurus passion.
But, as I said, Pisces and Taurus share a lot. The tranquillity of both enhances the other - the sensual charm and imagination of Pisces calms and inspires Taurus, while the general reliability and poise of Taurus brings peace to Pisces. These two soothe each other, and might very well indulge in any artistic activity together, with pleasing results for both. A promising combination.
