This is why the Cancer will dictate the slower tempo and Leo will fall for Crab’s charm, innocent looks, and opposite characteristics.
Leo – Cancer Sexual Compatibility
Cancer will be the one who will need more activity and newness, while Leo will look at sex as something mysteriously uplifting, but calm in its nature. And those differences could affect them.
The sign of Aquarius is the area of sexuality for Cancer. This is why this, usually shy sign, finds great joy in a different approach and perhaps sometimes strange ideas regarding intimacy. It doesn’t mean that anything is wrong, but Cancer simply loves action and variety.
On the other hand, this area for Leo is placed in the sign of Pisces, and Leo prefers romantic, dreamy, and even platonic, as sex without real sex, types of acts.
Leo – Cancer Spiritual Compatibility
In the terms of spirituality, Cancer and Leo will find it extremely hard to understand each other. Cancer will be dedicated to very personal, on one, and very traditional types of expressing faith on the other hand. And Leo will get spiritually inspired only through action and especially, history.
The real issue going on here is that they will have truly opposing views about everything deep, supernatural, or spiritually inspiring. Pisces is the sign of higher knowledge for Cancer and ecstatic religious experiences, deep insights and solitude will be the driving forces for a Crab.
At the same time, this area for Leo will be placed in the sign of Aries. And therefore, Leo will get inspired through military actions and history information, while this will look awful to Cancer.
Leo – Cancer Financial Compatibility
As far as financial compatibility goes, Cancer and Leo will function better than just average. Cancer will surely benefit from Leo’s mere presence. And Leo will show great prudence in all money-related issues. This is why they will have all chances to succeed, but if Leo takes the lead.
For Cancer, Leo is the area of direct earnings and any kind of relationship with Leo will simultaneously increase income, wealth, and generally, this union will create some big material desires which could be seen as a luxury.
This same area for Leo will be placed in the sign of Virgo, which is the area of close friendships and intellect for Cancer. This is why Leo will take control of their financial matters with great punctuality and skillfulness.
Leo – Cancer Intellectual Compatibility
Cancer and Leo will have truly mixed results exchanging ideas and while executing practical tasks. Leo’s habit to act with a certain nobility and always perform on behalf of a larger group or context of things will appear annoying to Cancer who will value neatness and savvy way of performance.
The area of logical thinking for Cancer is placed in the sign of Virgo, which is the area of financial flows for Leo. In this sense, Leo will respect 
Cancer’s ability to be precise and goal-oriented.
However, this same area for Leo is positioned in the sign of Libra, and too much talking and too little concrete efforts will get on Cancer’s nerves and make them insecure because the verbal expression is not one of their biggest strengths.
Leo – Cancer Summary
In general terms, Cancer and Leo will be able to achieve very nice emotional and even financial compatibility as long as they don’t involve in the other areas of their lives. The Cancer will enable the inner stability of their couple, while Leo will take care of their “public” presentation and plans.
