The LS FourthDimension is also gay-friendly, having several gay members belonging to it. As far as same-sex marriages go, they are still disallowed in Vana'Diel, but you can perform an unofficial wedding on your own, and take the rings from the wedding quest in San d'Oria (the one with finding the prince a bride) and do a couple of steps to inscribe your name on them, and trade it with your betrothed.
