about which an author writes is not part of the source's canon and that fan fiction about canonical same-sex relationships is therefore not slash. Femslash, a subgenre of slash fiction which focuses on romantic and/or sexual relationships between female fictional characters, on the other hand, are typically heterosexual in the canon universe, but when fictions focus on lesbian characters, the stories are often labeled as femslash for convenience. Original slash stories are those that contain male/male content, based on perceived homoerotic subtext between fictitious characters. This can be sourced from a variety of media content, such as manga, TV shows, movies and books amongst others.

The easy way around this is to pair all three together, or one member with both potential romantic partners.

Polyamory is not always caused by love triangles, but those that don't tend to be less accepted by the fandom. In some fan fictions, characters are given a polyamorous identity, including warning "poly readers that the central characters are monogamous."

Shipping a human character with an animal or furry character can be controversial as it treads a contentious line with bestiality. Age difference Controversial age differences have a wide range.
