Well, I suppose that may vary from one person to another, I myself can relate a lot to the MC. At least the me on my 20s, with all of that about the military dad, having to leave home because of him, being self conscious about my body in public places, waiting for something special instead of rushing into sex... There's a lot about that character that resembles the old me and makes it easy to place myself into the story. But as you said, that's relative.
