I'm a male, living in Belgium. I'm a DL only, I believe because of bedwetting until I was around 15 years old. Never used/got any protection, except for the typical brown rubber sheet. My interests in diapers started very early, one of the earliest things I remember came from kindergarden, where a 4 year old still wore diapers.
No special interests or hobbies, and I try to limit my DL to occasionally wearing.
