When a novel is primarily fantasy driven over romance, what is the appropriate amount of sexual content before it begins to feel like erotica? In the scenario that the sex is very emotional and does add to the character development, is it then the usage of certain words/explicit terms that might define it as erotica (if any)? If the love scenes don't detract from the main story, does it make a difference in how much sexual content there is in the fantasy? I would love to hear some opinions on this.
