I've had my port for about 6 years and I'm 13 years old now.
I'm a phobic of needles and what helps me get through the pain (sorry, there's pain) is I put some Emla cream on it (it's numbing cream...ask your doctor for some numbing cream). It takes most of the pain away. And...I listen to my iPod to keep my focus on the music.
Good luck!
