I have nothing against any of it, I get it really.
sure I wouldn't personally go for the extream stuff, I got a few tattoos and a lip piercing
my personal line is drawn at colored tattoos, but I don't mind others having them, and I consider a lot of bodyart, that I myself wouldn't get, as beautiful.
There is this really cool thing when you cut out a small sliver of your ear and tape the ear tips together so you get elven ears, that can look pretty cool, but I wouldn't do it my self.
Anchors are becoming more common and can be really nice, especially when used to enhance tattoos, and then comes tongue splitting, silicon bead implants, scarification, fake horns, tooth lengthening, it's all up to the individual, I wont mind.
but I think you should consider the possibility of you not being the same person in a few years from now, you'll perhaps be a person who do not think vampires are so cool that you'd painfully extend your teeth too look like one.
but then on the other hand when you do those extream stuff one will be unique, and for some people that is the definition of beauty.
I don't see why I should judge others because they have another idea of beauty than me.
I mean that goes for pretty much anything; breast implants, coloured lenses, clothing style, hair styles, and so on and so forth, not my place to judge as long as this person made the choice to have these modifications or styles because they them self want to and are not mentally ill (looking at those poor people who'd consider them selves ugly for that totally normal lookiong nose of theirs)
so when it comes to body art I draw the line on selfmutilization, such as cutting of legs and such, that is still considered an indication of mental-issues. (believe me, there are cases of people trying to get doctors to cut their limbs off because they think stumps are beautiful....)
