Last I checked, the Church is the bride of Christ, and the priest is His visible representative of that relationship.
In the simplest terms, taking a woman and making her the “husband” of the Bride is as perverted as same-sex marriage under any other guise.
I went to a Defending the Faith conference at Steubenville back around 1993 or 1994, and Peter Kreeft gave a talk wherein he said that we couldn't ordain women unless we were also prepared to endorse lesbian marriage.
I came home and told that to my wife, who was, at the time, an Episcopalian 100% in favor of ordaining women. She said, "That's ridiculous".
But 14-15 years later, here we have the denominations which started ordaining women talking about and/or actually doing, the blessing of lesbian "marriages".
The two agendas are very much linked.
