I'm a huge Kurt fan, and love to see him with anyone other than Blaine (big Darren fan, just not a Klaine fan).
I prefer well written, slow-build stories.
Favorite pairings for Kurt are Kurt/Finn, Kurt/Puck, Kurt/Dave. But I don't like stories where they talk once and are immediately in a relationship (see slow-build).
I also love Kurt/Finn friendship/brother stories, with interactions with Carole and Burt.
So, rec me your best. Self-rec included!
