Community Help: How much mature is too much mature?

I run the Blog GothSoap which I have put in the mature audience section. The posts are not going to be flat out Jason Vorhess and Freddy Kruger nor will they be XXX. It will be more like a Stephen King or Laurell K. Hamilton and a soap opera. I'd like to see it on the first page but having it under MA blocks it out. Can some one who is more familiar of the terms MA help me out here? Do I really need it in MA?

It's linked at this link.

Thanks Bloggers!
