Why do people seem to find chest hair attractive?

I just don't get it. I'm male and have chest hair and the people that I'm around or talk to find chest hair attractive on a male. Why? I usually shave it because I think it is unattractive and would rather have a smooth hairless body from the eyebrows/eyelashes to the bottom of my feet heels. But a lot of people seem to like it and tell me that they like how my body is naturally hairy and I shouldn't try to remove it and keep it natural. Is it normal to have chest hair or should I shave it?

The good thing is, I don't have hair growing on my back.

What is it about male chest hair that some people find attractive? I just don't get it????
