The vertical clitoral hood piercing (VCH) is one that most women are anatomically suited to wear. You can check to see if you are built for it by using the "Q-tip test" as pictured on this page:

When performed properly it is very quick and not an intense piercing. BE CAREFUL: many piercers have no specific training to do these piercings and I receive email daily from women who have gotten botched genital piercings! Do your homework and learn how to evaluate a piercer for competency and appropriate qualifications. You can learn everything you need to know in The Piercing Bible.

It is as fast to heal as an ear lobe piercing (as soon as 4 weeks), and most women find that direct the contact of jewelry against the clitoris is pleasurable and stimulating. There was even a study done that was printed in the American Journal of Obstetrics and Gynecology that stated the piercing improved "desire, frequency of intercourse and arousal."
