I received a message from a piercer seeking advice about male genital piercings:
A client came in a few days ago and asked me if it was possible to do a vertical frenum ladder instead of a traditional one. I wasn't too sure so I told him I would research and find out for sure before I would attempt it. I know this is one thing you are very well known for and your answer would be the one I would go by. Also if any of the healing or after care is any different than a traditional frenum ladder or other possible complications please let me know all you can. Thank you so much!!
One of the important considerations is whether the tissue is pliable in the area he'd like to have pierced. You may want to start with just one piercing, rather than a ladder, to see how he heals. Also, the success of this would depend, to some extent, on his size differential between flaccid and erect states. On frenums that go in the usual direction, they can rest somewhat bunched up and close together without it causing any trauma. Then, when the piercee is erect, there is more space between the jewelry.
However, in the vertical direction, this becomes more of an issue--especially if he has a large size differential. It would not be practical, and the jewelry would not rest comfortably or safely when he's not erect, and that would obviously mean this type of ladder works better in fantasy than in reality. If he doesn't change much in size, then it might be successful. Even on the most well endowed of men, you aren't likely to fit all that many pieces of jewelry in a row, as you'd want to use bars that have at least 5/8" post length. When you add barbell balls that are about 1/4" in size, you've got at least 7/8" length for each piercing.
Also, for penetration, he would likely find that the jewelry catches and causes trauma unless he plans to use condoms indefinitely.
This idea (of vertical piercing placements) will probably be more successful on a scrotum than the penis shaft, as the tissue is comparatively stable there.
I hope this is helpful.
