Introductions discussion

I have a petite shaft but seemingly substantial testicles. The only ring that fits both of them is the two-inch model. Getting it through the pin assembly isn’t impossible, just tricky. My main complaint is how the skin on my shaft gets caught between the center pin and the spacer, plus the way my balls get squeezed when I lock up in the cage. Since my penis doesn’t take up much room, the cage has to sit tight against the ring. That setup really compresses my testicles, leaving them with a dull ache. If I swap out for a longer middle pin or extend the spacer, though, only just enough of my glans fits into the cage’s opening. This turns peeing into a bit of a mess and doesn’t look very tidy either. Does anyone have suggestions on how to get this thing working without hurting?
