Darling you are an amazing kisser I miss you. 39 days left until i can kiss your hot lips again.

Hayatým müthiþ bir öpücüsün seni özlüyorum.  Ateþli dudaklarýný öpmek için 39 gün kaldý.

ps: However, "öpücüsün" sounds awfully weird to my ears, so if I were you I´d say "hayatým müthiþ öpüþüyorsun." which means roughly the same thing.. maybe you´d like to wait for a native to decide on that..

you are totally right

"öpücü" is grammatically correct but sounds very funny
