I can't remember whose advice it was about sex scenes, but they advised not to to get too detailed or creative, as any of your friends or family reading it would end up picturing you being the one engaged in those acts. Which makes me wonder how people in general look at the writer of "Fifty Shades".
I do recall hearing about a man who wrote a smut piece online about the girl band "Girls Aloud" losing his job because of it. Apparently the story was considered to ruin the reputation of his ex employer. I don't know the details as to how graphic the tale was or if it was even violent (I'd certainly understand them firing him for that kind of writing), but there has been plenty of various slash fanfic for various characters, both real life and fictional over the years. I can't imagine too many people losing their jobs or doing time because of that.
That said I don't think anyone would end up picturing the author of a story about the life of a fictional Olympic athlete, and see it being the writer taking first place and stepping up to get their gold medal on the stadium
