I am under the impression that, in the Catholic church, after confessing, people do penance (Our Fathers, Hail Marys, things like that) to gain forgiveness for their sins. If this is correct, what is the average* punishment meted out for: coveting another's girlfriend; lustful thoughts; masturbation? What if the lustful thoughts were about someone particularly against the rules, such as someone of the same gender, or a relative? Would these be general or regular enough that a frequent churchgoer could guess at them, ie do an Our Father (or whatever) after thinking lustful thoughts, because he knows it is what the priest would have him do? How does a rosary figure into all of this?
Also, any websites explaining, or explainations of, the various means of penance (and I really hope that's the word I mean, or I'm going to be very embarassed, and I do hope I haven't offended anyone) would be highly appreciated, but I'm sure once I know what to look for, I can google it.
Thanks very much in advance!
* If there is such a thing. To be more specific: the church is in Milwaulkee, Wisconsin, and is the sort of small church where families go for generations and everyone knows each other. The priest, to my knowledge, is neither a drunkard nor a child molester.
