Behind Closed Doors — Erin Lark

For Caleb, coming out to his parents is a lot harder than marrying Ally, a childhood friend, which is exactly what he plans to do. But even after he accepts her proposal to keep their sexuality a secret from both families, he can't help wondering if he's in the wrong or if the man he loves is just overreacting.

Shawn barely survived the bombshell Caleb dropped at his feet before storming out. Bewildered and entirely caught off guard, he admits he'd prefer Caleb cheat instead of hiding the truth, not to mention his love for Shawn from everyone but himself.

However, Caleb's secret isn't the only thing tying them together, and the more time Caleb spends planning Ally's wedding, the more he realizes he should be thinking of his own.
