I don't like Body Modifications, I like Tattoos...
Body Modifications like piercings are ugly as hell, make your tits/butt more bigger makes you look like a sintetic girl(for all the girls), and maybe too much body modifications can get you to an accident, maybe...
Tattoos are cool on my opinion, but not in gigantic proportions, like all of your body, even your genitals...
Maybe one or two in the arms or chest can be cool, the problem of tattoos are you can't donate blood to people who need it.
