Matt really enjoys hurting people, but feels guilty about it. In kinky sex, he takes the sub role because he's afraid if he was the dom he'd lose control and hurt his partner too badly, ignore a safeword, something like that.
Bonus points for Matt finally domming and actually losing control and ignoring a safeword and feeling terrible about everything.
Matt/anyone, Matt is a dom but always takes the sub role
