I had a little more trouble with mine than most would. The first time my friend pierced it with a safety pin, i took it out cause it kept getting caught on my pants. The second time the guy said I couldn't get a 14 awg (which is normal) because of the scar tissue from the first peircing so i had to get a 16 awg (which makes it really hard to find jewelry). You don't have to worry much about forcing it to move. When you get it soapy in the shower it moves by itself. it's pretty fun to watch.
Browniesmom-what's the scoop on getting the bottom pierced, your's looks so cool.
I've had mine for almost 6 years.
