horizontal clit hood piercing

I recently performed an anatomy consultation for a couple to help them discover which genital piercing the woman would be best suited for:  

Hello Elayne! My wife, J, would like to get a VCH or other genital piercing. We have read your book and have paid for a consultation. We live in northern Michigan and are planning to go to southern Michigan this weekend for the piercing. Before we go, we'd like to get your input.  Thank you so much for offering this service!!!

Please let us know if you have any thoughts about her suitability for the vch or horizontal piercings. Thank you so much for your help!!!

Hi J. 

In these images, it appears that she is a good candidate for a VCH piercing.

One concern I have about her getting an HCH or triangle relates to a visible vessel that could conceivably be in the pathway of a piercing. See the attached image I marked with an arrow to point out the area of my concern.

I received a message from a woman inquiring about a genital piercing:

 I was on a piercing forum and a girl made a post about a "high HCH" piercing. She didn't really go into detail, just mentioned that she has it. While I sent her a message for more info, I figured that if anyone could shed light on the subject, it would be you. I can't find any pictures or   info on the piercing aside from people saying that they have it. I was wondering what makes a high HCH different from a regular HCH piercing? How is the procedure different and would it be a viable piercing since I already have a VCH?

I would appreciate any info that you can give me and I hope you come back to Philly to pierce soon since i missed you last time!

Thanks, J.
