I can't answer this without going into several paragraphs because I have read A LOT of manga xD. And if you're going by just what's in your library I can't really provide a good recommendation because I have no idea what's there. But if you were to say, branch out online, then Hokuto no Ken (in no way girly, in fact quite bloody and graphic) and Angel Densetsu (fairly typical high school romcom) are good.
