badbad - i had no idea. you naughty girl.
my .02:
nose piercing can be attractive on some people. it all depends on the person. try to somethig plane and simple, like a stud or a ring. i typically see them on the left side of the nose but occasionally see them on the right.
eyebrow piercings are among the least painful peircings. i didn't even feel mine. i have also had mine in for almost 10 years now and it hasn't been rejected yet (it has puched out an ever so slight amount).
tounge piercings are fun for your partner.
nipple piercings are fun for you. i have both of mine done and it is well worth the cost (both the pain and the money). downside, it hurts when its first done.
belly can, again like the nose, be sexy on some people but not so much on others. i have known people who have had theirs done and they said that it was not really that bad. hurts a little more than your ear. i believe that it might even hurt more than the nose but i could be wrong.
south of the boarder is VERY PAINFUL according to everyone i know that has gotten it done. but they are also very happy with the end results.
as far as any scars when you finally decide to take out the piercing depends in large part on how well you take care of the piercing when you first get it done. if you take good care of it, then when you do take it out it should just close up to a tinny little hole, like on your ear. if you don't take care of it then it could get infected and cause scarring, mainly from the infection.
sorry i was so long winded. hope i was helpful to anyone.
