It’s widely held that the oval ring tends to be more comfortable than the round one. During my time in the HT, I found the smaller ring preferable because it kept my testicles snugly in place. The wider ring made me feel like my thighs were constantly shoving my balls forward while walking. Does anyone have thoughts on this? I’m worried about experiencing a similar feeling with an oval ring, and I don’t recall seeing many posts addressing that specific point.
