I am with a small (~20-25 people) GOA mission parish where the Divine Liturgy is celebrated only once a month, at best. We do not have our own building, so we rent a small Episcopalian chapel, which is available to us only on Saturdays. There is no real iconostasis there, and there is practically no space between the nave and the ambo, so it is difficult even to imagine, just where would penitents confess their sins if they want confidentiality. Also, the people who attend our parish are dispersed over vast space in the east-central and northcentral parts of our state. For our priest, who lives in Jackson, MS, it would take several hours to reach the place where we gather for DL, or the residences of most of our parishioners.
I guess these circumstances make routine, regular Confession difficult. However, I in fact have no idea when and where do the people in my parish go to confession. As far as I am aware, it may take place every day. Nobody ever talks about it though, and that's perhaps a good idea.
The Eucharist is always given to EVERY person who is Orthodox and present at the DL. I do not think anyone is ever asked the question, did this one confess recently, or fast.
