I probably have enough experience to be considered well informed on this topic. To go to the average tattoo parlor that does piercing on the side would be a major error if a woman is considering having her clitoris pierced.
If a woman must have her clitoris proper pierced, she needs to find an active piercer who can provide at least three references that she may talk to. Her clitoris needs to be, at the very minimum 5 mm. across. 8 mm. was as small as I would do as most ones attempted in smaller clits will heal out with bad scarring and subsequent loss of sensitivity. Read what I just said again, it is very important to understand this.
The piercing should be placed through the glans clitoris, not through the shaft. If possible it should be done at 14 gauge, but most have to be done at 16 gauge. This piercing will take 60-90 days to heal superficially. For heavy play, I would suggest waiting at least 6 months.
I did 4 clitoris piercings in my active career. I have since done 2 for friends who deeply wanted this and were highly motivated in addition to being anatomically able to have it.
The only piercers I know of who did more are Elayne Angel, who is not retired and Michaela Grey who is no longer in any way associated with the body modification field.
A clitoris piercing is not for a sissy. All of my clients have said it hurt worse than anything they have ever experienced.
I should point out that I come from the very conservative Gauntlet trained community of piercers. Almost everything I learned was from people who were trained by Jim Ward or one of his acolytes. Strangely, on some things, like avoiding small gauge intimate piercings, I tend to agree with that blowhard, self-promoting con man, Todd Bertrang. His big mouth put him in prison. The last I heard he was seeking someone to castrate him.
