I guess I think its nature.
I think its because someone who has a very similar upbringing doesnt nessicarily end up being a CDer. Luca had a really crazy family. But was drawn to his sisters and mothers clothes. I think when your first sexual experience is with women's clothing, there is some amount of nature to that. If that wasn't the case, would luca still be a CDer. I think probably yeah.
While I don't believe CDing makes someone a certain way "more emotional, loving, caring, or whatever". I think the same is true the opposite, someone who is raised in a certain environment that does not make them a CDer.
