As a general rule, the Sanguine and the Choleric personalities will not usually find each other very attractive; however, if they manage to fall in love, the union can be a very strong and bonding one indeed!
Their conversations will be interesting because both are very intellectual personalities. The Sanguine person will have broader interests while the Choleric person will master fewer topics, but his or her knowledge within these limited topics are deeper.
Both of them will look at each other with admiration – the Sanguine will admire analytical and rational mind of the Choleric, and the choleric will admire curiosity and width of knowledge of the Sanguine.
Both of these personalities will require a high degree of autonomy and independence. They are both self-sufficient and to top this off, they are both busy with plenty of stuff going on for them outside of the relationship. This is perhaps why none of them will be too demanding, controlling or unreasonably jealous in any given situation.
Their different ways of interaction with the outside word also will not create any problems, simply because both of them can admire the traits of the other.
For example, the Choleric is often straightforward and can even be insensitive in some cases. All he or she cares about is to getting to the point in the shortest way possible. Sanguine people are adaptive, like chameleons, adjusting themselves to what needs different circumstances at hand will require from them. Still, the Sanguine will admire the candor of the Choleric while the Choleric will love the ease with which the Sanguine communicates with other people.
On top of this, a Sanguine personality is usually hedonistic and extravagant, while the Choleric is more self-controlled and disciplined. Nevertheless, the Choleric partner will love the utter spontaneity of the Sanguine while the Sanguine will have fun loosening up the emotionally-contained Choleric person.
They still might face some problems because the Sanguine is optimistic while Choleric tends to be skeptical; sometimes the Sanguine will see the Choleric cold and cynical, while the Choleric will think that the Sanguine is taking unnecessary risks due to his or her impulsiveness.
Although both are competitive, they have very different approaches to the competition. While Cholerics tend to be very ambitious; highly focused on the goal and openly aggressive, the Sanguine is more relaxed and wants to enjoy his or her multiple interests. As a result, Choleric partners may see Sanguines as lazy, and regard some of their playful activities as silly, while Sanguines might decide that Cholerics are simply boring.
Still, above all of these differences, the two personalities have a high level of compatibility and may make a great match in potential love situations.
