Why would a man want to wear earings? That is my question.

I can't answer for nowadays, but before the Victorian era, lots of men wore earrings.

The practice dates back to antiquity, and 99.9% of earring-wearing men were sailors, merchant traders, adventurers or other people who frequently traveled far from home, and were likely to die in a faraway place.

The earring the sailors wore (and it was usually only one) was made of solid gold or pure silver.  It was supposed to be used to pay for a Christian burial if the sailor died in a foreign land, or if the body washed ashore among strangers.

Yes, I looked this up.  I was sooo into Adam and the Ants at the time, I found myself facsinated with all things Pirate.  I read novels and history books about them.

I still love pirates.  I just recently visited the Pirate Museum in Salem, Massachusetts.

I don't know why people wear more than one earring in the same ear at the same time...

I have two earrings in each ear, but I got the second set of holes to "fit in" during a time when all my friends had five or six holes in each ear. ::) ::) ::) ::)

...But I'm much better now.... ;)

I was told that earring holes would eventually fill themselves in again if unused for a long time. Is this correct? Do they still leave a scar? End Quote

They do not fill thenmselves in. They get a bit of scar tissue in them, but it's more like a crud that washes away.  :P

The holes will never close all the way ever again.

I know from my own experience and the experiences of others around me, who have been waiting for their "mistakes" to close up for years.  :-/

What kind of a statement is being made by wearing two or more rings in one ear? I just don't understand this. Is it just because somebody else is doing it and therefore cool? Isn't that conformist behavior? I thought teen fashions were supposed to be about being non-conformist.

Is wearing multiple earrings considered Goth or Punk, or what, exactly?

--Earring holes that are not used for a long time do fill up with some kind of crud.  Dead skin cells. :-X :-X   The myth of scar tissue comes from the fact that most people who don't wear their earrings for a long time tend to forget the angle used to put the earring in.  Then when they try, they "miss" and poke good skin, causing pain. (Trust me on this. Been there, done that ect.)

--Teen fashions and behaviors are only non-conformist to the extent that they are trying to be as unlike the adults as they can. They do still want to fit in with their peer groups, so will try not to be too different from their crowd.

--As far as two or more earrings in the same ear, I don't think it could be considered Goth, Punk, Pop or anything else.  When my crowd was doing it, none of us could have been considered either Goth or Punk, not by any stretch of the imagination.  I think it is just to do with what is currently fashionable, like how long a skirt should be.  One year above the knee,  next year below the knee, the year after that mini-skirt, the year after that, mid-calf and so on.
