The Stud by Christopher X Sullivan

An asexual man is now in a sexual relationship with a male model… and is in over his head.
Chris and Mark’s relationship evolves. Both men learn to depend on the other during trying times. Chris is in the closet with his family, but Mark doesn’t add pressure and remains a solid support. Meanwhile, Mark is struggling to reconnect with his parents and older sisters and Chris is the catalyst that enables the vain male model to return home.
All good things must come to an end, and if you’ve read this far in the series, you should know that the last few chapters of this book contain the long-foreshadowed Big Fight.
This self-portrait was written as a romance… but not every story gets a happy ending.
