I'm not looking at it on that level. I see it as a fashion trend. Some people wear Armani suits and drive fancy cars while others poke a bolt through their face.

Just cut out the "it's a personal choice" bullshit because it's not nor has it ever been.
And yes, sometimes those tunnel plugs are sexy as fuck. It's unfortunate that my needle penis can't get enough friction to get me off.
