It's sexual, but not quite. I sometimes wear for quite long and than it's mostly "hey, I'm in a diaper" and that's it. No real change, except the obvious ones. But when it comes to sex or masturbation it becomes very arousing.
It's kinda weird when I think about it, but I never really understood that people say they are relaxed and it helps them to fight stress. It's not the case for me, but it would be really awesome if it could. Do you think it can become like that? Can you somewhat make yourself associate being safe, calm and relaxed with wearing?
