There are only a few possible combinations between the sun and venus, here are the descriptions of the blends from ARIES VENUS to CANCER VENUS:

• ARIES VENUS
  

Sun in Aries / Venus in Aries

Here is a very passionate and enthusiastic partner who needs to maintain independence within a permanent relationship. Although selfish at times, they will be generous to loved ones, wanting them to enjoy the relationship. Money is often made from sidelines as well as a main source, and investment will be enjoyed. Impulse buying can lead to cash flow problems. Rivalry can occur in friendship, with the individual needing to take the lead.        

Sun in Taurus / Venus in Aries

The passions are very powerful, and while one may make an excellent, sensual lover, the emotional level is so high that storms may well arise. At such times possessiveness (Taurus) and selfishness (Venus in Aries) can cause serious problems, but the highs will be marvelously romantic as well as fulfilling. Over-emotional reactions can sometimes also cause difficulties with friends. In money matters, they are clever, but a liking for luxury may diminish resources.

Sun in Gemini / Venus in Aries

The Geminian mistrust of emotion can cause problems with this passionate placing, but there will be good rapport and friendship, and sexual fulfillment once the tendency to rationalize is overcome.This is a lively friend with many varied interests, wanting to do a great deal and travel widely. Spendthrift tendencies must be countered.

Sun in Aquarius / Venus in Aries

This adds warmth and passion to the cool detachment of the Aquarian Sun. There will be powerful emotional relationships, but sometimes conflict can arise when the subject has to decide whether to deepen one of these through cohabitation, and there may be a delay in making an emotional commitment. Independence is most important, as is the Aquarian lifestyle; there will be an active social life and many like-minded friends. There is an erratic attitude to money, with a liking for unusual possessions.  

Sun in Pisces / Venus in Aries

The sensitive watery emotion of Pisces combined with the fiery passion of Aries makes one an ardent but caring and tender lover. At times the individual will be confused by their own emotional intensity, and apprehension and a lack of self-confidence (Pisces) may clash with a desire for the loved one (Venus in Aries). Nonetheless, the striving for a rewarding relationship is important, as are friends with shared interests. Money will be enjoyed, so saving may well be difficult. The subject may find that impulsive generosity could cause problems.

• TAURUS VENUS
  

Sun in Aries/Venus in Taurus

This will increase the affection and add passion. They approach love affairs with surprising caution, but must realize that selfishness and possessiveness can cause more damage than might be imagined. Enthusiasm and prudence should be combined to get the best of this placing, both emotionally and materially. They are an excellent friend and good company, with an infectious enjoyment of life. Financial enterprise is combined with care.  

Sun in Taurus/Venus in Taurus

The Taurean characteristics are very prominent and could outweigh the power of the Ascendant. Love and the attitude towards money and its making are as described under Venus in Taurus, with all Sun sign characteristics complementing, enhancing or exaggerating those of Venus in Taurus. The metabolism could be slow and Taurean ailments may be present. The weight should be strictly controlled by restricting the intake of rich food. Financial and emotional security is of vital importance.  

Sun in Gemini/Venus in Taurus

This increases the Gemini emotional level, but can cause problems, since one must learn to express their emotions and not over-rationalize them. They must try hard to counter any possessive tendencies.They are a lively, talkative friend who will enjoy organizing events. Quick Gemini wit will complement the Taurean business ability.  

Sun in Cancer/Venus in Taurus

There is marvelous potential for being a caring, sensitive and extremely sensual lover. However, the Cancerian tendency to cherish and protect, combined with a Taurean leaning toward possessiveness, can create highly claustrophobic conditions within a relationship and have an adverse effect on family life. This is a friend who is faithful but easily offended. Business potential is superb, with Cancerian shrewdness adding to Venusian flair.

Sun in Pisces/Venus in Taurus

This adds stability, and is a good counter to Piscean elusiveness. The emotions are steady and tempered with common sense and fiscal ability. A practical approach both to love and financial matters is often present, and the placing will add to the creative flair of Pisces, helping to give it concrete form. As a friend, they are more reliable than most Sun sign Pisceans, but an element of possessiveness may emerge within relationships.

• GEMINI VENUS
  

Sun in Aries / Venus in Gemini

The ardent passion of Aries is tempered with light-hearted affection and an attractive expression of feelings. Infidelity and trying to get the best of both worlds is common, often hurting the permanent partner. Arian selfishness and a quick response to tricky situations will be seen when the individual is challenged. Partners with good minds as well as bodies are essential. Intellectual competitiveness is welcome within friendships. Arian financial enterprise is increased here, sometimes giving the ability to sell well.  

Sun in Taurus / Venus in Gemini

The love, passion, intensity and natural charm of Taurus are enhanced. As Venus rules this sign the whole personality will be lightened, possessive tendencies reduced, and the overall Taurean slowness corrected, both intellectually and physically. This is a friend who enjoys intelligent conversation and good living. The need for possessions as material security will be tempered. Alertness and quick thinking in business will be an advantage.

Sun in Gemini / Venus in Gemini

The powerful influence of Venus in Gemini will be very apparent, and any tendency to over-rationalize the emotions should be countered as it can cause inhibition. The emotional level must be assessed in relation to other areas of the chart, especially the Ascendant and the Moon sign and their aspects. There should be a talent for making money.  

Sun in Cancer / Venus in Gemini

This adds a much-needed rational streak to the sometimes overwhelming Cancerian emotion, and steadies the tendency to worry unduly about loved ones. When choosing a partner intellectual rapport and friendship are essential, as is mental stimulus. Views will be freely and even sharply expressed but Cancerian faithfulness will still be evident. Shrewdness will be shown in business deals.  

Sun in Leo / Venus in Gemini

Enthusiasm and the need for love and affection are spiced with flirtatiousness, while friendship and a progressive relationship are essential.There is a good blend of well-expressed emotion and a rational approach to joint problems. The partner must be able to enjoy life and be generous both emotionally and financially. Bossiness should be countered, especially towards friends. Extravagance and a clever financial flair are usually complementary.

• CANCER VENUS
  

Sun in Taurus / Venus in Cancer

Passion and sensuality are heightened, with love and affection actively shown. Possessiveness may mar the relationship. The emotional level is extremely high and there may be storms and scenes at times. One must learn not to cling to loved ones after a relationship has ended. Look for logic in other areas of the chart - the position of Mercury, perhaps. This is an affectionate but possibly demanding friend. Financial ability and an excellent business sense are likely.

Sun in Gemini / Venus in Cancer

This heightens the level of Geminian emotion and, provided one doesn’t over- rationalize the feelings, these will be marvelously and romantically expressed, showing kindness and a cherishing quality. The sex life must be lively and stimulating. This individual is considerate and a good communicator both with friends and loved ones. Financial security can be gained from collecting old or unusual artifacts.

Sun in Cancer / Venus in Cancer

The emotional force and expression of love are very powerful, but the inclination to worry over the partner and family is immense, and the Cancerian capacity for caring may also get out of hand with friends. Here the qualities are very much as for Venus in Cancer. Shrewdness in business matters is a strong asset.  

Sun in Leo / Venus in Cancer

The emotional level is very high, and one needs a partner to look up to and admire, otherwise there will be a tendency to dominate with a Leo bossiness that can be extremely harmful. Leo sensitivity is greatly increased; this individual may suffer more than seems possible. There will be a great appreciation of quality and the beautiful things in life, with a lot of money spent on them. Comfort, security and quality are important.The sex life will be rich, rewarding and imaginatively expressed. Here is a caring friend with excellent organizing ability.  

Sun in Virgo / Venus in Cancer

Although there will be considerable emotional resources, there may be shyness and reserve in expressing the feelings. The imagination will be rich, but worry over the loved one’s reactions can be inhibiting, especially in young people. There may be a tendency to criticize the partner or be very moody. The household chores or hobbies can be used as an excuse for failing to enjoy the intimacies of a relationship. A clever business sense is likely, but sometimes meanness is present.
