When should I use the ‘Sex’ and ‘Gore’ tags?
This is simple enough: use ‘Gore' when there is explicit description of violence/grotesque imagery in your story, and use ‘Sex' when there's... well... sex. On a Teen-rated story, ‘Sex' can be used to indicate sexual humor or situations that are heated but don't have explicit sex, while ‘Gore’ can be used to indicate the presence of blood or violence that isn’t described in too much detail.
