Is a marriage between a transman and transwoman in accordance with Roman Catholic canon law? The transman and transwoman can still engage in intercourse to make babies, but the transman would be the one to get pregnant, assuming that they still have functional sex organs. I am asking this question, because I am not sure whether transsexuality itself is a sin or whether the act of going against procreative sex is a sin. I believe the answer may reflect how the clerics will handle a case where the participants involved in the wedding are one transman and one transwoman.
