I feel that it would be valuable to have the ability to rate and see a rating for how big of a component romance is of a book and if there is any sexually explicit content included.

This would allow both adult romance readers to see books that may appeal to them, as well allowing young readers, romance/sex repulsed readers, and those simply not looking to read heavy romance in that moment to make a clear informed decision without doing extensive research that often does not answer the question of how big of a component romance is to the story.
