Do it if you want, but be prepared to have people judge you irrationally for it. Also, if you're planning to go down the huge "I can stick my finger in" size holes, make sure you're ready to live with the consequences forever. I met a guy I knew from school, he had the huge ones put in. When I saw him months later, he'd removed them but was left with horrible looking dangly lobes that had barely stuck back together. Not nice.
So yeah, I'd stick to the smaller ones.
