With regard to the rite of Confession, this rite is, and always has been very vague in terms of the exact words to begin the confession of sins.
In the Extraordinary Form, according to the 1962 Roman Ritual:
15. The penitent says the “Confiteor,” either in Latin or in the vernacular, or at least the following words: “I confess to almighty God and to you, father.” Next he confesses his sins in detail…
Likewise, in the Ordinary Form of the 1973 Rite:
44 Where it is the custom, the penitent says a general formula for confession (for example, I confess to almighty God) before he confesses his sins.
(no link as I typed that from the printed ritual, and the part in parentheses is in the original)
We can clearly see from both forms that there neither is, nor has there been any set formula for the penitent to begin confessing sins. We are all familiar with some “traditional” formulas, and these have been composed as a way to help penitents begin the actual confession part. These traditional formulas are neither required, nor were they ever suspended or forbidden.
The key phrase in the new rite is “for example” That clearly means that a penitent can use any reasonable formula to begin the confession of sins. There is no such thing as “it’s not done that way anymore.”
As long as the penitent actually does confess the sins, there is niether any right, nor any wrong way of beginning the confession (ie, the actual listing of sins). And please keep in mind folks, that this applies to the Extraordinary Form as well as the Ordinary Form.
Some typical examples:
I confess to Almighty God, and to you Father…
Bless me Father for I have sinned (it has been XX since my last confession and these are my sins)…
Bless me Father, I accuse myself of the following…
Bless me Father, for I have sinned, I am XX years old and married/single etc. It has been XX since my last confession, I received absolution and have performed my penance, I confess the following sins…
Of course, we see a lot of “mix and match” among the phrases used above as well.
Sometimes a penitent even begins with the words “It’s been a long time, and I don’t know if I can remember what to say…”
