SUN VENUS ASPECTS IN SYNASTRY. GENERAL
The Sun represents our ego, the conscious self, what makes us special, what personal achievements make us proud. It is also a symbol for authority.
Venus shows our values, how we do relationships, what we find pleasure in and is also a representation of the partner.
In a Sun Venus synastry we see how one person's ego is interacting with the other person's sense of value, their love language and projection of a partner. Venus is usually a permissive and tolerant planet. Even in the hard aspects Venus will try to please the Sun and although hard aspects with this combination will result in one person being oblivious to the other's way of showing love, any combination of Sun Venus will give an atmosphere of tolerance and acceptance of the other's ego.
SUN CONJUNCT VENUS IN SYNASTRY
In the conjunction we see that the Sun person's ego and identity is in a perfect match with what the Venus person finds valuable and what they are looking for in a partner (this could be platonic like a friendship or romantic).
Venus projects it's idea of a perfect partner onto the Sun and the Sun usually is delivers what Venus expects. The Sun may feel very proud because the Venus person has chosen them. Venus can not only tolerate any egotistical behavior or sense of grandeur of the Sun, but can also find this attractive. This aspect is great for forgiveness and gives potential for a long lasting relationship because it can compensate any other negative conflictual aspects between the two. The two people feel at ease with each other. The Sun person knows that Venus will accept and love them for who they are. Sometimes, the Sun person can get an inflated sense of self from the Venus person. If this is not a double whammy the Sun person may be the dominant one in the relationship and act as a authority, but the Venus person does not mind, because the dominant characteristics of the Sun are similar to her value system.
The Venus person's love language is well understood and received by the Sun. To have balance in the relationship the Sun person's Venus or Moon should also be involved in the synastry, otherwise only one person is getting the love and appreciation of the other. Because Venus also represents money and gifts, the Venus person could shower the Sun person in presents.
