You can have it at least in three versions: It could be in your birth chart and it makes you very loving and loved at the same time. It can be a transit, and it’s a very favorable one and an excellent aspect for getting married and conceiving. And in third option it occurs once a month and it’s most of the time a superb day, marked by strong sexual and emotional links. It’s the best aspects for romance. There is increased emotional stability and a sense of harmony, since we share uplifting and nurturing feelings with ease.
The Moon and Venus in conjunction shows an ability to relate very easily to people. You find it easy to be friendly with just about everyone. Occasionally, you can be so friendly that you may arouse suspicions in some more jaded souls. You’re never one to wait for the other person to make the first gesture when introduced, and you can put anyone at ease with your affable ways. You are extremely responsive to friendliness and abhor rudeness. There is little pretense about you. You act the way you do simply because you think it is and because of your early training.
This can be a very poetic aspect. Kahlil Gibran has it in Sagittarius and this is how he describes a love relationship (note the Sagittarian sense of independence and the need to have and give more space to the loved ones):
“Let there be spaces in your togetherness, and let the winds of the heavens dance between you.
Love one another but make not a bond of love: let it rather be a moving sea between the shores of your souls.
Fill each other’s cup but drink not from one cup.
Give one another of your bread but eat not from the same loaf.
Sing and dance together and be joyous, but let each one of you be alone, even as the strings of a lute are alone though they quiver with the same music.
Give your hearts, but not into each other’s keeping. For only the hand of Life can contain your hearts.
And stand together, yet not too near together: For the pillars of the temple stand apart, and the oak tree and the cypress grow not in each other’s shadow."
