Is it wrong to enjoy wetting myself and wearing diapers?

I've got a very week bladder, so I have been known to wet myself on accident. I wasn't potty trained until I was 5 1/2and I wet my bed until I was 9. I've always had a fascination for diapers since I was very little. Even when I didn't need them anymore I would wear pull ups and have "accidents" in them. When I was 10 I hit puberty and my fascination became a full blown fetish. When I was 12 I bought my first pack of goodnites. I was given a fairly large allowance so supply was never an issue. By the time I was 14 I was wearing to bed every night, and now that I'm 15 and have a job I can afford to buy several packs a week, so I'm pretty much always wearing a diaper. Recently though I've discovered that I also enjoy wetting my pants without a pull up on. I especially enjoy this out in public. For the most part I've never told anyone. Just a few girlfriends, one of which was a bed wetter and another who wanted to become involved. Is any of this wrong, I'm not really hurting anyone, but I still feel very guilty.
