My friend and I were discussing lesbian marriage and she asked me what legally constitutes non-consummation for the purposes of annulment, and I realised that I don't know.
I think with hetero marriage it was PIV, because a friend got an annulment by swearing on oath that he was unable to do PIV owing to complete erectile dysfunction. Of course that would not "work" for a marriage of two women.
So I wondered if anyone on MN knew what the legal definition is of consummation between two women.
