Watch:
Really Reccomend:
Hanbun no Tsuki ga Noboru Sora
Karin Chibi Vampire
Maison Ikkoku
Kimagure Orange Road
Tenchi Muyo (All of them)
Chobits
Macross (I suggest you watch the old ones and work your way up)
Zegapain
Cross Game is very good, but very light on romance (Don't kill me Sackett)
Suzuka (Damn good one)
Midori No Hibi
Tonagura
I really liked N.H.K, though really, minimal romance
Full Metal Panic, you can just feel the romance, but you never see it
School Rumbe, love this one
Ginban Kaleidoscope
Koi Kaze
Kare Kano
Lovely Complex
Boys Be
Genshiken
NOT RECOMMENDED!!
Onegai Twins (if you watch this, I recommend you keep away from guns and alcohol)
Onegai Teacher (Same as above)
Gift Eternal Rainbow
This Ugly yet Beautiful World
Check my list for some ideas
