You can always take it out if you find you don't like it down the road. I say go for it if you think you might like it, but think long and hard about it. If you get it done, make sure the place is sterile. They should show you the needle in the package before they open it. Don't be cheap with hygiene and go someplace $10 less--You'll pay for it with the healing time.
I wanted my lip pierced basically from the age of 13 'til I got it done at 19. Kept it in 'til I was almost 21--Ended up taking it out because I realized it didn't look very good. Not to mention work changed their policy on facial jewelry and wearing a retainer in the hole was a pain in the ass.
I also played with it wayyyy too much and it got irritated frequently--If you have any oral fixations (or if you like inflicting pain), you may not want to get anything in/around your mouth pierced. So easy to play with it 'til it hurts then not stop... /rambling.
In general I think they look all right on some people who get it--But others just can't pull it off.
Oh, and anything but hoops may scratch your teeth. I wore a straight gem in the lip piercing hole for awhile 'til my dentist yelled at me and mentioned how it was wearing away the enamel.
