Recommend me Manga

The title say it all.

So... I'm looking for a good Romance manga. The problem is that I don't like (so much) Shōjo. I'm more into Shōnen & Seinen than others. But, if it's a good manga and have some romance on it (even if it's Shōjo). Say it, name it, write it. Something like... Good Ending or Ane-Doki.

I have read the following ones (Who have Romance):
Ane-Doki
Bakuman
Bitter Virgin
Cross Game
Good Ending
Kaichou wa Maid-sama
Kyoukai no Rinne
Lilim Kiss
Skipt Beat!
The Devil and Her Love Song
The World God Only Knows
