As a gift last Christmas, I received a bar piericing in my hood. It turned out to be the best gift I have ever received. The additional stimulation has definately incdreased the intensity of my orgasms.

And, if you would like to "fancy" it up a little bit, you can find bars with gemstones and dangles for special occasions. I wouldn't recommend wearing the dangles for an extended period of time (more than 12 to 18 hours), but they can be fun in the right situation.
