I just started reading this story. Forrm the first chapter, even before Greg met Kyle, I thought he was projecting himself. Maybe because I'm European, where ages of consent vary from 14 to 16, the age difference is not a big problem for me by itself, as long as there is no manipulation and lies. Well, even in the us, depending on where they are are, the age of consent might be 16, so Kyle might be close (some states have 17 or 18). We still don't know what exactly happened with Greg, but he was either groomed and manipulated to have sex and then hurt and abandoned, or actually raped, so it's understandable that he fear the attraction he is feeling, he doesn't want to do what was done to him. Maybe Kyle will actually help him heal.
