Natural family planning

[Jehanne]

1484 "Individual, integral confession and absolution remain the only ordinary way for the faithful to reconcile themselves with God and the Church, unless physical or moral impossibility excuses from this kind of confession."95 There are profound reasons for this. Christ is at work in each of the sacraments. He personally addresses every sinner: "My son, your sins are forgiven."96 He is the physician tending each one of the sick who need him to cure them.97 He raises them up and reintegrates them into fraternal communion. Personal confession is thus the form most expressive of reconciliation with God and with the Church.

‘The form most expressive’ explicitly establishes that there are other, acceptable forms.

Sacramental confession is normatively required for the forgiveness of mortal sins; it is not absolutely required. What this means is that, in extraordinary circumstances, mortal sins can be forgiven outside of sacramental confession. If a Catholic is dying and cannot go to sacramental confession, his mortal sins may be forgiven if he repents with true contrition (i.e., sorrow for sin) and has at least the implicit intention to go to sacramental confession if the opportunity is made available.

The website catholic.com was founded by Karl Keating, and it is not an official Church site, unlike the paragraph that I cited above, which is from the current Catechism of the Catholic Church. Point is that sacramental confession is not optional, at least if one is Catholic. But, as the paragraph that you cite above loosely states, if moral (catch all?) or physical impossibility prevents such, salutary repentance can suffice, at least until absolution in sacramental confession can be obtained later on for a penitent. But, such is not "optional".

Again, stirring the bullshit clockwise versus counterclockwise.
