Monogamy among Wiccans

Whether handfasted or married in a courthouse (for mixed marriages [like a Wiccan married to a secular Jew for example]), Wiccans should be monogamous.  Orgies are wrong.  The Lady and the Lord are monogamous.  I would want to death do us part, but if there is a split-up, Wiccans can have a hand-parting ritual.  It is much a "no hard feelings" ritual where they still care about each other.

To add something, sex magic without love is black magic.
