Chastity and orgasm denial discussion

I recently placed an order for a jailbird. I’m also considering getting a pair of deep dydoe piercings:

The image gives a fairly clear view of the piercing in question. The main concern is clearance. With a deep dydoe, you’ll have two barbell beads sitting just behind the coronal ridge and another pair on either side of the urethra. If those rear beads cause any trouble, I can use a dremel to grind down some metal. My real worry is about the beads flanking the urethra.. Could someone who owns or uses a jailbird measure the distance between the two bars that run lengthwise along the top? The device I’m getting has a diameter of 1 3/8” and is 2 3/4” long, so measurements from a similar unit will work (they don’t need to be exact). Ideally, I’d like the measurement taken from the center of one bar to the center of the other; that way, I can subtract an 1/8th inch to account for the thickness of the bars. It would also be great if someone could share a photo showing the tip or underside of their device where the head of the penis typically rests. This is especially helpful if they are fully erect so the penis is pressed firmly against the cage’s ends. Most photos I’ve seen of a “filled” jailbird show it from above or the side:( Thanks ahead of time.. Since dydoes and chastity are somewhat new areas for me, I’ll write up a post detailing how (or if) they work together.
