I have 59 titles on Amazon and they cover all categories and many genres. Liquid Memories, Hero In The Hood, YODO, I Want To Be Openly Gay, The Mark Unmasked, Less Pretty and many others have what you call less graphic language because it fits the story lines and characters. I concentrate on what feels natural and more authentic for the story, setting and dialogue they would probably use in real world situations. Readers will reject something that does not feel right given who characters are supposed to be and backgrounds they come from.
