Do you have one?

Here's a question

I have one
Your husband will have one
Your mother uses your father's one
And your auntie use's your uncle's one
A married lady would acquire one
But a divorced would lose her one
A pope doesn't have one
Madonna doesn't have one
The chinese usually have short ones
While the pakistanese ususally have long ones
After your marriage your husband will give you his one?
Longer or shorter you have to take his one
Do you want one?
How long do u want?
Which one is your preferred one?
Long one or short one?

what's that??
