Any stories where the uke is a playboy going from guy to guy, but them meets the main seme and falls for him? Maybe his playboy past causes problems for them, but in the end it works out.

I would definitely recommend Honto Yajuu, if you haven't read it already.

You can also check out the tag "Playboy/Playgirl Becomes Monogamous" for more stories, since I am not all-together that familiar with that story type myself.
