You tend to share the same interests and cultural values.

“When the Sun in one chart forms an aspect to another person’s Venus
Conjunctions, sextiles, and trines between the Sun and Venus are helpful aspects in any relationship. They create a sense of harmony and offer some common interests to the partnership. The Sun person feels more loving and beautiful in the presence of the Venus person. The Venus person finds the Sun person quite charming and intriguing. The Venus person admires the Sun person in such a way that he or she is willing to, and happy to, please the Sun. There is a mutual attraction here that, on its own, is not as insistent or sexual as other indicators (such as Venus-Mars or Venus-Pluto), but it is pleasing and supportive. Acceptance and tolerance characterize the partnership. Perhaps the most apt keyword for this combination is contentment. On a financial level, unless debilitated, this combination suggests some financial “luck” as a couple, or at the very least an overall agreement on how to spend and save money.
In particular, the conjunction suggests that the individuals find much to like in each other. Little qualities in each other that might seem commonplace to other people take on grander, more romantic, and valuable proportions in both Venus and the Sun’s eyes. It is easy for the Sun person to draw out affection and tolerance from the Venus person, unless either planet is seriously debilitated natally. The sextile is not as powerful or obvious a connection, but it generates a feeling of mutual respect. The people see value in one another—they’re most certainly worth each other’s time! The trine is probably the most fortunate of aspects between the Sun and Venus in synastry. The individuals truly value each other. The only potential pitfall with the trine is complacency and lack of challenge, although it is more than likely that there are challenges elsewhere in the comparison, and in most cases this interaspect helps support the relationship.“ http://www.cafeastrology.com/synastry/sunvenusaspects.html
