In any case, the individual will be attracted to someone who has a good set of values and appreciate the pleasures of life.
On the other hand, a Leo rising needs friends, a friend; is it possible to find The friend? Or just lots of friends...He may attract detached partners, friends who come and go and the idea of detachment needs to be scrutinized. The position of the Descendant ruler is key to the type of partner, in this case Uranus.
A Cancer rising attracts or is attracted to more conventional types. They want structure and also stability. The partner could be older or colder than him. The Cancer rising may provide the emotional care that his partner lacks.
A Sagittarius rising is very much looking for mental stimulation with his /her partner; they are cheerful and like someone with who they can laugh with while conquering the world. Sometimes, there could be 2 major relationships in their life.
A Gemini rising likes variety and freedom in his relationships. He could be very much attracted to foreigners too depending on the position of Jupiter in the chart. In your search for a perfect relationship Venus-Neptune aspects especially beware, real communication could be aborted.
Look at your Moon and Venus position if you are a man; your Mars and Sun if you are a woman. The Nodes, South or North may also bring past life partners, karmic relationships and tremendous potential for growth. 
South Node contacts can bring sudden recognition (past life connections).
The 7th house planets, natal or in transit are vital to the analysis. Any Solar arc transit to the Desc can bring change or a new relationship.
All synastry signs the deal.
