With Eros in the 7th Sagittarius you regard your partner partially through the possibilities of enhanced erotic experiences. It doesn’t have to be just sexual, it can be also spiritual and creative. That is also the “special something” that you look for a partner to really feel fully engaged in a relationship.
Your Venus in Pisces supports this attitude with deep sensuality, as well as Mars on Scorpio. They both add a dimension of a necessary emotional commitment in a relationship. You kind of open and close your gates in an attempt to hold on to the best the you can both receive and give.
All of this would work just fine together, but Uranus in the 7th can be very confusing, because it seeks to liberate – pulling you in the opposite direction from Mars and Venus placements.
Your configuration is not a fixed pattern and it will develop as you grow older. As you become more accepting, flexible, and egoless in relationships, they will work better for you. Don’t look in the past as your Venus demands from you. Overcome quickly, and look strictly in the future to avoid emotional stuckness.
Good luck, and be at peace with unique qualities you bring to your relationships!
