I love anime Clannads(AF), ef - a tale of melodies, ef - a tale of memories, Elfen Lied, Angels Beats, Ah! My Goddess, Seto no Hanayome and more.
I also enjoyed Hokuto no Ken.
I like romance "told" from main male lead perspective and situated in today's world with some sci-fi, magic or supernatural element in it. (But i can do without sci-fi, magic or supernatural too )
I prefer strong male protagonist over so called "wimps".
I also came to like anime Hokuto no Ken but I'm having hard time finding something with protagonist like Kenshiro (battles could be less symbolic thou).
I'm not too fond of over the top ecchiness, but i don't mind it if it's not disturbing story.
So that's me and my anime preferences (simplified).
