Venus opposite or square Mars:
There is a strong sexual and romantic attraction here as well, but often there is some sort of problem with timing. The Venus person tends to think of the Mars person as too crude and aggressive. The Mars person usually thinks the Venus person is too stuffy or uptight. Compromise is necessary in order for this to work out well.
Moon conjunct Venus:
This is a very benevolent union. It creates harmony and sympathy in romantic relationships, partnerships, marriage and business. It creates a similar value system so that the two will be in agreement in financial and social issues. It is often an indicator of intimacy.
Moon opposite or square Venus:
These two people have conflicting desires and needs. Often the Moon persons need for security in is conflict with the Venus person's desire to socialize. The Moon person may seem too clingy to the Venus person and the Moon person often feels that the Venus person is insensitive.
Or in case you're confusing an opposition with a quincunx..
Moon aversion to Venus:
If present reciprocally it is an indication of a lack of intimacy or interest in eachother or it can mean that unrequited love may be an issue.
Venus trine or sextile Saturn:
While this combination can be a bit staid, it is very helpful in creating a relationship that lasts a long time. Each is very respectful to the other. It is capable of creating long and stable marriages that have practical benefits such as stabilizing joint finances.
