We are a small chapel. Each Sunday the line at the confessional wraps around. Sometimes a priest hears confessions after Mass because there is not enough time. I try not to guess who has been to confession or not but its easy to tell. I'll say most of our members go to confession at least once a month, some go every week. I am usually somewhere in between, but I feel like I could go every day sometimes. If I don't have a chance to get to confession, I do not go to Communion. I am not alone, though.
When I was NO, I went to confession about once every 4 or 5 months. IF confession had been on Sunday before Mass, I probably would have gone more often. It was not convenient to go to confession at 2:45 on Saturday afternoon. (Yes I know how that sounds, but it is true.) Of the times I went though, there were only ever 2 or 3 people there. And we only had confession during that time period, unless otherwise requested. Yet on Sunday there were at least 12 or 13 Eucharistic "ministers" between the two Sunday Masses....just saying.
