Abnormal cookie fascination?

Ok, I know this is a bit weird but ever since I was a small boy, I've had a thing for oreo cookies. I don't know, it's just something about that creamy middle. Well, I'm all grown up now but this cookie fetish still persists. Sometimes when my wife and kids are gone, I'll get a whole bag, make tall oreo skyscrapers and take off my pants and masturbate all over them. I don't eat it, that's groze. But I do like to photograph it and send it to strangers on the internet. I'm a professional photographer, BTW.

I know it's probably abnormal and should see a psychologist, but I can't seem to stop. Is this really weird, or do other people have similar experiences? Please help...
