Erections at night

[BlackoutDevices]

Edit: Another part is actually the ring shape, which unfortunately for most cages, a circular shape is not very anatomically correct. So depending how your testicles like to sit and how your erection interacts with the ring, it could cause issues from that alone.
My logo is actually based on the base ring shape that I use for my Evo, which you can see how there is intentionally designed room for the veins to sit in the "corners" of the ring (the bottom black area) so that there is still good circulation during an erection (the blank middle space)

what's the timeline on your sport model?

Its still in a very early prototyping stage so likely not till fall or winter 2021
