Now if you want to talk specifically about "lesser urges" which I suspect is another way of referring to masturbation without coming right out and saying it, you might be surprised what a practicing Catholic in the state of grace with the help of God is capable of avoiding. It also helps to be married. ;-)
This is not to say that I have never been guilty of mortal sin...absolutely have....but not on a weekly or monthly basis as you suggest. Catholics that go to confession on a regular basis and receive Christ in Holy Communion while in a state of grace receive additional graces to combat such sins.
Really???? So, now, you're saying that you can "earn" graces? Totally incorrect! Grace is freely given by God to us NOT for anything that we do but as a true Gift from Him!! Grace cannot be earned by works.
