Need Advice on Going with a Smaller Ring

Hi everyone. I’ve been using the Holy Trainer v2 for a few months now, with my longest continuous wear lasting three and a half weeks. It’s wonderful because you barely notice it on your body. I take it to work (I’m a firefighter), go swimming, play sports—you name it.

One thing I’ve noticed is that when I get a solid erection while wearing it, the cage pushes down slightly as intended. However, once I lose my hardness, I can easily pull out without issue since my testicles stay in place. I plan to buy an anti-pull-out device soon and will share my thoughts on it then. Also, if I don’t wear supportive underwear underneath, the whole unit tends to slide down a bit—not excessively, but noticeably.

My question is: should I switch to a smaller ring? Currently, I’m using the 45mm size with the small tube. When soft, there’s just enough room (barely) for a finger between my scrotum and the ring; it feels quite secure. However, along the sides near the locking mechanism and down through where the penis sits in the tube, I can easily slip space between the cage wall and my skin.

Any advice?
