A good portion of my book takes place in the context of a group of high school hockey players. From personal experience I know the kind of foul language that gets thrown around in locker rooms and in groups of guys in general. My question is whether it is exceedingly vulgar to use realistic language for these situations. It's written from the point of view of one of the players, so he also uses that kind of language himself. It doesn't bother me personally to read bad language; my eye starts to ignore it after awhile. I'd like to know what everyone thinks about excessive swearing in fiction. I feel it is necessary to achieve the realism I want, but how much is too much? Is it more advisable to cut down on the swearing but risk the realistic sound of the dialogue?
