I should clarify, you may have a confessor, but not a spiritual father, per se. Your confessor may be your de facto spiritual father, but, things can be complicated here. IMHO, real spiritual fathers are rare and not everyone has one.
"For although you have many tutors in Christ, you have not many fathers," said St. Paul.
This is very true. All the priests are our spiritual fathers, and the parish priest is who put in charge of our local parishes is all of our priest in the singular sense, but individuals to have a deeply involved spiritual father in the individual sense is indeed very rare. I don't know what I would do without mine, he is so much more a father to me than any other man could be, and it has entirely been by the grace of God, because initially I didn't even really like him very much!
To the OP:
(1) Spiritual Father in the plural sense is a title applied collectively to all priests for all Christians, because they are our spiritual fathers, not necessarily our literal fathers (though sometimes both

in fact I asked my confessor, "Abba, did you ever think that you would call your sons Father?" to which he laughed and said not at all), but they serve as paternal figures in our spiritual lives of prayer and growth in our relationship with God and with the Church.
(2) Confessors are priests who receive a special blessing by the Bishops to hear confessions and give absolution. Not every priest is a confessor, in the Ethiopian tradition generally confessors are limited to monk-priests. The Latin Catholics actually have special university level training in psychology for their confessors.
(3) Regular priests are the everyday priests in the Church, who may be monks, priests, bishops or all three combined

In the Oriental Orthodox priests can be married, but not monks, and Bishops must have been monks first.
All priests are spiritual fathers, but only rarely to folks have an intimate and involved relationship with a priest they call them my spiritual father in the singular-possessive sense, and all confessors are priests but not all priests or spiritual fathers are confessors. In other words, if A then C, if B then A and C, and all C are A but not all C are B.
stay blessed,
