Good concept, mg. It would be nice to have something to set the two apart...(hmm, cogs turning) unless there are some who want the "cover" of being able to say they're married, without revealing the gender of their mate. However, that has nothing to do with your idea. I'm afraid I can't come up with anything other than the mundane: partnering, mating--oops, scratch that one; hey, wait--how 'bout cleaved?
