Moon in 1st House synastry gives your partner a high sensitivity to your appearance and your direct personal manifestations which affect them very much. Your personal reactions are related to your partner’s lunar manifestations: you will enjoy (or dislike) his or her care, and you may be jealous if they take care of someone else.
If your partner’s Moon is harmonious, you will enjoy the coziness they exude; but they will probably want to get more from you and your personal manifestations than you can offer (a poor Moon always gravitates towards parasitism), and then the most courteous of your partner’s manners (attempts at friendly embrace, etc.) can cause you irresistible disgust, not inferior to the power of joy that embraces you during the warm periods of your relationship.
In same-sex unions, Moon in 1st House synastry may not be very pronounced; in contrast, in multi-sex unions, it is likely to be very pronounced. If the woman’s Moon enters her partner’s first house, he will be highly dependent on her whims and moods, and all her desires will act on him, maybe more strongly than direct instructions and commands. This, however, does not mean that he will comply with them (this requires an aspect of his Sun or Mars to her Moon).
If a mother’s Moon gets to her daughter’s first house, the girl may grow up with a severely deformed, subordinate personality, and the mother will be attached to her daughter much more than vice versa: which, unless the mother controls her selfishness towards her daughter, may lead to a riot and rupture in adolescence, youth or immediately after marriage, when the rights to the girl’s 1st house will be offered to a young husband who will take care of her upbringing or re-education.

Moon in 1st House Synastry Explained
Moon in 1st House Synastry involves the formation of a strong emotional connection in high in importance relationships between people.
Self-expression of the First House’s personality provokes emotional responses of the “lunar” personality. If the Moon is somehow connected with the Fifth House of at least one of the horoscopes of these personalities, then we can most likely talk about the emergence of a romantic relationship. Family and household chores are the main color in which these relationships are colored.
A Hymn to the Moon in 1st House Synastry – Goodnight Moon by Shivaree
The identity of the First House seems to have a definite effect on the home life of the “lunar” personality, which implies a strong emotional connection in the factor of family relations. For example, a child brought up under such conditions may subsequently not feel emotional independence from parents even after becoming old.
In the relationship governed by Moon in 1st House Synastry, both individuals are prone to memories of their early childhood and distant family habits and traditions. This stimulates the development of the corresponding psychological reactions. Whether these reactions have a generally positive or negative impact on the dynamics of the development of relations between these people depends on other important factors of this comparative aspect, as well as on the aspects of the Moon.
In some cases, the “lunar” personality can begin to annoy the person of the First House with his emotional problems and mood swings, and if the aspects of the Moon are unfavorable or the whole comparative aspect is rather complicated, it is likely that the personality of the First House will depress the “lunar” one emotionally.
