I got mine done about 7 years ago. I like it. I'll take it out eventually, but whilst I'm young I want to enjoy my body how I see fit. I don't show my stomach except for when I'm at the beach or whatever, so I don't see how it can make a girl seem easy unless she's got her guts out all day.
In my opinion, you can't "look easy" anyway. Being easy is about behavior . Granted, appearance can affect how people judge you and whatnot, but those people don't matter anyway. Hold yourself with class, confidence and dignity and you won't have to worry about looking easy.
I love belly rings. They look very hot in my opinion. I don't have one myself cause I can't sand thinking about the actual pain involved but if you want it get it. And it's definitely not easy at all. In today's society it's quite common.
Yes, of course. That's why they've become so mainstream and popular.
I'm not really sure what to say to this question other than yes, they have, that's why so many people outside of the original groups who got them have them. That's why so many new piercings have been invented and so many tattoo shops opened. Also why we have a TV show about it.
