I'm good with all kinds of Anime and Manga really, as long as the plot is good. I don't think age has anything to do with it, it's just your personal preference. Most Manga and Anime have some sort of mature content so there really isn't anything Du can do about it but adapt! Just find something Du like and ignore the parts Du don't like, it's called imagination. :)
Here is a site full of suggestions so go pick one that Du might like and try it out. If Du don't enjoy it then continue searching until Du find one Du do!
