That would be news, I'm sure, to the many dozens of Anglican and Episcopal priests who have been received into the priesthood of the Roman Catholic Church under the "pastoral provision." Nowhere has it ever been said that those *married* Roman Catholic priests have to give up marital relations with their wives.
Not true. It may not be said very often as a part of polite conversation, but a dedicated commitment to continence by both spouses is a requirement within the pastoral provision for the reception of married protestant ministers into priestly ordination within the Western Rite. The basis for this can be found in Canon 277 and a more detailed explanation of its development in "The Pastoral Provision: Ordination of Married, Protestant Ministers" Canon Law Society of America proceedings #51 by Richard Hill, S.J.. This is a contributing factor, I'm sure, to the vast majority of converting ministers choosing ordination to the diaconate or a lay pastoral role (it would be for me!).
