Hi y'all!
I'm looking for a manga (or anime) that has a girl main characterl that falls in love with a guy her age or older (if guy is younger the guy can't be younger than 2 years). They don't have to fall in love right away and it can be very slow at first. Please no incest, yaoi, yuri, and perverted guys (they can't only like her because she has like big boobs or something). I don't really care if the art sucks and I'd prefer if it was a kinda long series (but it doesn't really matter). I don't mind there being some sex, but please not a manga just about sex. I like shoujo mangas so far, but I haven't really read any other genres, so it doesn't matter what the genre is. And finally no guys that are completely useless and are weaker than she is. Thanks!!!
Some that I'm already reading/read that I like:
Skip Beat
Gakuen Alice
Lan Chi (not much romance, but I really enjoy the story)
Abide in the Wind
Sukeban Deka
Vampire Sphere
Virgin Ripper
Witch Workshop
Oresama Teacher
Oh! Lord Jesus (guy kinda weak but whatever)
Kubera (ik it's not really what I said I liked, but I like this one a lot)
Glass Mask (I love the guy in the manga so much!!!)
Dear Waltz
Ciel- the last autumn story (love this so much)
Akatsuki no Yona
Azumi

I know I'm kinda picky, but if you know of something please help. If you can't think of anything please just put something that you think is somehow related to it. Thanks again!!!!

Actually your description coverage is really wide so I'm just going to recommend some of my fave:
Kare Kano
Kiss
Teruteru x Shounen
Basara
Tokyo Crazy Paradise
Youko x Boku SS
Meteor Methuselah

You could always try Kanata Kara, Boukyaku no Shirushi to Hime, Tsubaki-chou Lonely Planet, or Sengoku Danshi Hana no Ran. Kanata Kara is probably the longest.
