Bwah hah hah...
I was raised by a hyper-religious family (read:cult) and have attended more hours of church (read:extreme boredom) than whole groups of people combined, which is probably why I'm an agnostic and will not even set foot in a church for weddings or funerals.
And, probably, why fresh-scrubbed makeupless girls in long dresses still give me serious wood (read:no outlet for teenage hormones), and probably why, well into my fifties, I'm still very good at masturbation (read:no outlet for teenage hormones).
This is one of those subjects where "You just woulda had to have been there." There is no real way to describe some of the crap I went through as a child. To the bizzare "foot washing ceremony" and the pit of horror (read:baptism pit in cellar of church)... it was unreal... I still cannot talk to my parents about religion, or this stuff... amazing. Amazing what we put our children through, before they are old enough to understand stuff. I tried to be fair to my daughter, and let her know what was out there, but I did not pressure her into anything.
I'm sorry I got off on that, I realize that wasn't your question...
Yes. I've had boners in church. More than I care to remember. I've even whacked off in the bathroom at church, while hearing long droning boring sermons in the background. Good grief, what I'd have gave back then to have a phone full of porn to look at, instead of just my fervid imagination. And a glimpse of an occasional ankle. Jeezus. Give a guy a break.
Our upbringing seems to determine a lot about ourselves. I accept that mine is the reason I'm so weird, and probably so hostile about things most people don't even think about much of the time. Like church. Sorry, god, old buddy.
