I want to be a writer but the only thing that motivates me to write is themed around stuff that turns me on [Conflicted]

From someone elses point of view the writing will look normal but i know that its come from a dirty place in my mind and i hate it, i get normal ideas all the time but im never motivated however when i think about my fantasies i cant wait to write, i dont want my writing to be based on sex but its the only thing that gets me to write.
