Are there any yaoi where the whore uke falls for the main guy and tries to stop his whoring ways. The problem is his previous partners causes problems for the main 2's relationship. Maybe the whore uke relapses once, but then regrets it.

(Not all of these have conflict caused by a "previous partner," but their conflicts do stem from the uke's promiscuity. Hope they match what you're looking for 😀 )
