Until I was in my early 20s, I was very pious. I went to mass most Sundays, said the Rosary regularly and really bought into the whole thing. Anyway, despite this, I never went to Confession, from when I was a young teenager. I found the whole thing completely embarrassing. The priest is a man, there's no getting away from that. I could never feel comfortable telling another human being my inner most thoughts. I never actually had any proper sins to confess, so everything would have been things I was thinking (bad thoughts about other people, etc). It just seemed wrong. The only problem was that missing mass is a sin and you're not supposed to take communion, if you've sinned and not been to confession. So, every so often I'd not take communion, as I'd missed mass the previous week. But, then I'd start taking communion again, giving the impression that I'd been to confession. All the time, I hoped the priest thought I just went to another church to confess, because they know who's behind the curtain. The stress that it all caused me was part of the reason that I stopped going to mass altogether.
