I didn’t imply St. Paul was never ever married. He may have been a widower, like St. Peter. I just meant he was celibate by the time he was writing the Epistles, as he himself attested. And as he recommended.
Please note that Catholics not only believe that marital sex is good -— we believe it is Holy, a constituent element of a Sacrament, and thus a channel of a specific Sacramental grace.
And interestingly, celibacy is not.
There's no record of Peter being a widower.
1 Corinthians 9:5 Do we not have the right to take along a believing wife, as do the other apostles and the brothers of the Lord and Cephas?
