Cursing in novels

I've been seeing a lot of articles online about whether or not it's good to have characters curse in novels, so I decided to put in my two cents. One of my all time favorite novels features a character with a potty mouth (Deb from Dexter), so I'm not against a character cursing if it is part of who the character is. People curse in real life, so it makes sense for some characters to curse in a novel. There does come a point where the cursing is too much and it becomes distracting. I, personally, don't have that much cursing in anything that I've written. I only use profanity to build character. Well, that's my take on cursing in novels. :)
