Belgium has had gay marriage since 2003, the second country in the world after The Netherlands. Canada came third, in 2005.

In 2005, Belgium saw what is perhaps a first: a civil union of three. Belgian marriage cannot comprise three partners, but apparently a civil union can.

Although it comprises one man and two women, it’s not a true polygamous relationship. In traditional polygamy, one man has two or more heterosexual wives. The union is typified as a ‘V’ by those who study the subject, with one party (in polygamous relationships, the male) as the sexual linchpin of the union.

In the Victor-Bianca-Mirjam union, the women are bisexual, so the sex involves any combination of the three, making this perhaps the first officially recognized polyamorous union in the western world. Or the entire world? That they’ve existed before, with or without the male’s awareness, must be a given; I don’t know, however, that a sexual triad has ever had any official recognition in recent history.

One commenter observes that “what gay marriage is to homosexuality, group marriage is to bisexuality.” For Mr Kurtz, this possibility is a bad thing; for me, an urban Canadian female of European extraction, it is entirely fascinating.

My concern is with the balance of power. A relationship which gives all/most of the power to one party (traditionally, the male), with the other party(ies) being dependents, is a bad thing, no matter how “normal”, “traditional”, or legal it may be. That a union of three or more is more relationally/emotionally complex than a union of two is inevitable: the more parties, the more interactions, the more layers of emotion, needs, resentments, goals.  But though it may deter some, complexity is merely a challenge.

If the parties are equal in the relationship, and equally satisfied by it, can this variant be a bad thing?
