I need just a second to hop up on my Soap Box, so please bear with me a second this might get rambly and a little offensive. Just know that if it doesn’t apply, let it fly!!
Are they the same or are they different? The definitions seem awfully close, however, I see a few differences. The word artistic being one of them. Writing is an art form, not everyone can do it. Just because Amazon, Blogger, and other self-publishing platforms make it possible for people to self-publish, doesn’t necessarily mean they should. Publishing Houses, content editors and copy editors exist for a reason. I am not by any means saying that people should only go the traditional route. What I am saying is before you hit submit on your story you should run it past a few people that AREN’T friends or family to make sure you have the best story possible. Especially if your end game is to make money.
Now to tie in the above definitions. Writing a story that is 90% sex and 10% story is not Erotic fiction or Erotica. It’s freaking PORN. PERIOD. Don’t try to pass it off as a story especially if there isn’t one there. I am all for sex in my books. It’s a part of everyday life(married people may disagree)and in all honesty in romance and/or erotica I expect it to happen. What I don’t expect is more humping than dialogue. What I don’t like is unrealistic stories. I get that it is fiction, however, when people read romance novels, erotic or not, they want to escape, put themselves in the heroine or hero’s shoes. They want to be that person if for the few hours they are reading. You can’t do that if the story has no substance.
Just remember, any idiot with a camera or camera phone can have sex, record it, and upload it to PornHub and get a bunch of views. That doesn’t make it good porn, but the point is to sexually arouse and although that is the point of erotica, don’t be the idiot with the crappy camera phone porn.
