It's just something I've always been interested in, it's hard to explain, I guess to me it's the same as why do people have their ear pierced, why do people get their nose pierced, why do people like certain cars or bags or shoes......just lifestyle preferences.
I have 10mm wide tunnel, so not that big, and if stretched in the correct manner, they will shrink back again to close to original size.
If I need to, I wear one of THESE to make it more discreet.
They have minimal damage risk if done correctly, like most things.
Mine are clean and hygienic and certainly don't smell!
And also, KerryMumbles link, photo number 3, is John Lynch, I've met him and he's a really lovely and sweet man.
I respect that it's not to everyones taste by all means, but comments such as
"All so cheap and common and rough.
Attention seeking"
....are just unreasonable
