What's a good romance, crossdressing, or (e)cch(i) manga. ?

I haven't read a lot of manga, or just books in general. I'm not much of the reading type. But when I do I get really into it. I've read Afterschool Nightmare, and that's about all I really fully finished. But I have watched a bunch of anime such as Ouran Host Club, Kaichou wa Maid-sama, Toradora, and even little bits of Kiss x Sis. I've watched the dramas of Hana Kimi and Hans Yori Dango.
