I can't say that I have any stories like that, and I grew up Catholic. I don't recall ever meeting any Catholics that used God as a way of getting something for free.
I was just referring to the whole, "if it feels good, it's a sin" mentality.
That's partially a joke, but it's rooted in reality. I'm not trying to bash Catholics (as I have a great deal of respect for people who are Catholic), but it's not really my thing.
