A lot of what he'd first snapped at Steve had been parroting, but there was still some very real fear beneath it, and even though he'd loved Steve for years and had come to love kissing him, touching him, laying in bed with him -- there were still things that made him want to go back to that kneejerk reaction, and that was the last thing he wanted to do. Being shirtless was fine, but now he was worried. What if Steve wanted more than that? Could he give that to Steve, or would he end up breaking what they had?
