One of the groups I belong to is MFRW, which is Marketing For Romance Writers.
We are on Goodreads, and I'm the librarian in charge of adding books to our list when they're published. We have the authors give us the genre. So if you're interested in, say, paranormal romances, the check out that list. If MC books are your jam, we have a category for that also. We even specify whether or not the erotic book is BDSM--or not. www.goodreads.com/group/bookshelf/161092-the-mfrw-book-place
When I add new books, I leave them at "Currently reading" for a month. Then they move to "Read." But the genres remain the same.
BTW, we also have a blog, Romance Lives Forever, that features a new book and author every day. This is another great place for you to find your next favorite book/author. www.rlfblog.com/
