When going to the Sacrament of Reconciliation some basic principles of courtesy are needed.
First, if you know you need to have over 5 minutes then schedule an appointment. Since the Church calls us to go to Confession often there really should not be a long list of sins and spiritual counsel needed, unless for some reason one is not confessing all their sins and is concealing them out of pride.
Second, the use of lists is not necessary, confess the sins that come to mind as one has reflected on the Ten Commandments and the Commandments of the Church and in true humility confess them quickly, receive your absolution and do your penance. Also, be mindful each priest has developed his own method of doing the sacrament. Some want you out quick, some desire as stated earlier for you to do a form of light spiritual direction with them, and some want you to to take your time. But regardless of the methodology a priest uses be mindful of other penitents who are also seeking the cleansing laver of the Sacrament of Penance and make it a truly heartfelt and yet brief confession.
Third, know the difference between spiritual direction and the advice a priest gives in a confessional. Spiritual direction is not to be done by a confessor generally during the rite of Penance. Spiritual direction entails seeking a spiritual father or mother to assist you to come closer to God and grow in holiness which leads you to frequent and good confessions and a deeper more full relationship with the Trinity. The confessor is to offer the penitent short and yet valuable advice on how to avoid the sin committed and the occasions of sin, give the absolution, and the penance. Some priests may even listen and not give any advice, then give the absolution and offer the penance.
Fourth, do not be overly scrupulous in finding fault with yourself or looking for sins under every bush–a practice which also leads to many unnecessary confessions which take up the time of the priest when your soul is in a state of grace and you are not either in mortal sin or have very few venial sins which can be forgiven through the use of sacramentals such as holy water and receiving the minor absolution at Mass.
Fifth, go with God; and I hope my advice can help someone, for it took me many years to learn the manners of attending the Sacrament of Confession.
