hope it's the one you are looking for :)
yaoi about a guy that had multiple personalities but the reader never saw him as those we would always see him as him. He would always wake up from the personalities having sex with another guy (who we find out is his boyfriend), the boyfriend (uke) would each time appear with more and more bruises each time he showed up
