As Natural As Breathing (All They Ever Needed Book 1) by Thianna Durston

For Christian Darringer, life isn't worth living. Just back from the Middle East—scarred and with permanent damage to one leg—he doesn't think anyone will want him for anything. He didn't plan on meeting someone he can’t stop thinking about. Pulled toward the startling younger man, he begins to question a lot of things—especially his sexuality. Not one to hide from a challenge, he plunges ahead only to find himself more than just attracted to Logan. Logan Mannette has almost everything he ever wanted: loving parents, happiness, friends, and security. The only thing missing is the love of his life, a love just like his parents have. When he meets Christian at a party, everything changes. Instantly attracted, he does his best to help the sad man and quickly finds himself feeling more than he has ever felt before. Raised in a domestic discipline household, he holds that ideal as what he wants. His interest in spanking has become a fetish and when Christian admits he wants to be spanked, Logan believes he might have found the perfect man. Just as everything begins for them, Christian's past intercedes and one of his brothers makes waves about him dating a man. When it lands Christian in the hospital, he is forced to reevaluate their budding romance. Being with Logan might feel as natural as breathing, but if it costs Christian everything he cares about, is this new relationship worth it?
