Family, Love, Romance
Relationships will be developing in zigzag, as a lot will depend here on a Sagittarius' partner. If he or she is patient enough, the year may be regarded as successful; at any rate you will not be bored for sure. Anyway there is a significant danger of going too far, and you will have to work seriously at self-improvement so that you could preserve peace and quiet in the family, if there is one, and if you don't wish to destroy it.
But at the same time stars foretell liberty of flirting for Sagittarius. You will arouse genuine interest in others, and many of them would give a lot for a bit of your attention. Holiday affairs will be especially demonstrative in this respect.
Beware of the overwork, especially in autumn; various awkward situations connected with sex failures are possible. Even continence is recommended for a week or two (and may be more - depending on your own perceptions), just to feel more confident. That will also make you burn stronger with desire.
