Same case with Aria
There are Gokujou Seitoukai, Otome boku wa koi ni shiteru, My Hime/Otome, Maria+Holic, Venus Vs Virus, Rose of Versailles, Magister Negi Magi, Azumanga Daioh. I'm not sure about Utakata, but in the end of the series the main characters who are two women have kissed.
Yuri or half yuri :
Sailor Moon S and SS
Onisama e
Bakuretsu Tenshi
El cazador de la bruja
Noir
Hack Sign
Ikkitousen Dragon Destiny
Loveless
Kashimasi girl meet girl
Kyoshiro no towa to sora (or Kannazuki no Miko 2nd Season)
