Heard on (I think) a news segment about gay marriage as spoken by a wedding officiant, "You may express your love with a nuptial kiss." (I wrote this down some time ago and just came across the bit of scrap paper that I wrote it down on).
I love the complete gender neutrality of that statement. We may go with that for our wedding smoochies.
Come to think of it, I would prefer that all the vows be as gender neutral as possible. I shall have to think about that as we get into the actual vow-writing.
