Just finished reading "Yield Under Great Persuasion" by Alexandra Rowland and it's so fucking good!! 
Picture, if you will, a very bitchy male protagonist who is allergic to feelings and his long suffering, endlessly patient fuckbuddy of almost two decades. They have a fight when the fuckbuddy finally loses said (not so endless) patience, and from there these two start growing into better people, together.
There are also fantasy gods, magic and a fair bit gay sex, which never hurts 
To sweeten the deal, in case you weren't already running to purchase the book, the very first sentence goes like this: "Tam Becket did not care for Lord Lyford. On the other hand, gods, the man had a cock on him".
I was instantly hooked
I sat down and read 300ish pages in one night. I might be a little sleep deprived but I can't regret this decision, I just *had* to know what happened next!
