A manga is a Japanese comic; what makes it different from American comics is the drawing style, and the fact that while American comics are like illustrated books, manga is like a movie in book form; that is to say, it doesn't have as much Pagsulat as an American comic (in general) and it takes, on average, about half an hour/an hour, to finish pagbaba a manga volume, depending on how fast you read.
Yuri is girl pag-ibig and generally means that the manga has smut scenes in it; if you want a manga without smut scenes but which still has girl love, try looking for shoujo-ai mangas, which are still girl pag-ibig but which are generally restricted to halik or holding hands. The male counterparts for yuri and shoujo-ai are Yaoi and shounen-ai, respectively.
