I would argue that there are no legally married same sex couples, since such a union can’t be consummated due to the biology required.
And which state requires consummation for a legal marriage to exist? Because of physical disabilities, not every heterosexual marriage can be consummated. And those marriages are very valid!
I do not agree. There are many asexual people who are married. Not sexually consummating a marriage does not make them less married than you and I...well, not you and I...you and your spouse and me and mine...sorry.
