it's probably no surprise after reading the title of this thread - I'm a DL from Germany and live near Frankfurt. I can't say for sure how i got interested in diapers. If I remember it correct my interest started when I was 14 or 15 years old. I have never worn diapers on a regular basis, there were even times when I thought I had lost my interest in them - but somehow I wind up in them every now and again.
Other 'hobbies' of mine are biking and going to the cinema.
