According the law of the universal Church, crystal clear in the rubrics, clarified with official statments from the Holy See, when there is a footwashing rite during the Mass of the Lord’s Supper on Holy Thursday, only males may be chosen to participate (viri selecti).
On the other hand, in very many places this specific and serious requirement is ignored.
Keeping in mind that the footwashing rite is an option in that Mass, and it may be left out for a good reason, what was the practice in your parish THIS YEAR.
Thus, you will probably have to wait to answer this until you see it happen… and no doubt you will because you are going to go.
I went to the Mass tonight at St. John Lateran and was seated in choro just a few scant meters from the Sovreign Pontiff. The sermon was fabulous.
I can assure you that the Bishop of Rome washed the feet of men.
