I like to chew on a synthetic dog bones intended for small dogs - am I weird?

Hi,
I have a pretty weird situation. I always have this urge to chew on anything chewable really. Bubble gums are too effortless for me. Pens, pencils, my own fingers etc. Every time I get this chewing fixation, I'd usually go and buy myself a medium-rare sirloin steak. But recently, it has gotten worse.

I recently purchased a "small-dog teething bone" on Amazon and it reached today. I instantly started chewing on it and felt nice and relaxed.

So my questions are:

1) Is it weird for a human to want to chew on a dog bone? (just to be clear -not the bone of a dog but a cosmetic/synthetic store-bought bone meant for dogs)
2) After chewing on it for 10 mins, I feel a slightly gratifying yet weird sensation in my jaws. Should I be worried about harming my jaws?
3) The bone I bought is intended to be for very small dogs to chew on during their teething phase which means it ultra soft - but still tough enough for humans. Is it okay if I keep chewing on it?

A few details about me:
1) An omnivorous diet (70% meat 30% everything else)
2) I smoke (there may be a connection)
3) I'm a 30-year-old male with strong teeth that I generally take care of
4) I can chew food/fruits/other edible stuff better than other people around me.
