I had a "Frenum" done about 18 months ago. Girls like it alot, but I couldn't stand it. You had to take it out to masturbate, or for Oral Sex(unless your gf doesn't mind chipped teeth), and it hurts to do that, since the threading where the end ball screws on, rips against the inside of the piercing as you pull it through the pierced skin. Also, I kept it for like 8 months, and don't think it ever healed properly. Not to mention that it hurt like a bitch getting it done. Not worth it imo.
