I've never seen a girl with it done though.

A
Christina piercing, also known as a
Venus piercing, is a
female genital piercing. It is located where the
outer labia meet, below the
pubic mound.
[1] The Christina piercing is a
surface piercing; it has a high
rejection rate, and is not possible for all women due to anatomical variation. The piercing does not facilitate sexual stimulation and can be found uncomfortable when pressure is applied.
[2] It is usually pierced with either a custom made
circular barbell or
surface bar to reduce the risk of rejection. If the recipient's anatomy allows for it, a
captive bead ring can be worn after the piercing has fully healed.
Like most surface piercings, the Christina piercing is of contemporary origin. The first known Christina piercing was performed in the 1990s. As is common practice in the piercing industry, it was named after the first recipient of the piercing, a woman named Christina. It is also occasionally referred to by the less commonly used term "Venus", in reference to its placement at the
mons Venus.
The piercing usually heals in 3 to 4 months, but as a surface piercing, it can lead to complications during the healing phase. Further difficulties develop due to the relatively long piercing canal and constant movement and friction. In addition to being susceptible to infection, the Christina piercing may also wash out.
