Okay, probably the most important question- do you have a Kindle or Kindle app? :D I get most of my m/m books as e-books.

Right off the top of my head, you might like the Raised by Wolves series. There are four books. The first two have the most to do with the two main characters' relationship, the latter two have to do with family complications (which I can understand given the time period, but is not one of my favorite things to read about.) The first two books are among my favorites, I love the protagonists and the buccaneer stuff. I'm about due for a reread on these, actually.
