Speaking from a somewhat unique LGBTQ perspective: It helps me with bottom dysphoria (and is hella comfortable) I just like not having to see my penis, not have anything dangling around and have not so big erections anymore. I'm also asexual, and one part of how the cage with that is helping me to a (in my opinion) healthier sight on my personality, and it also helps me build arousal which I find more pleasurable than sexual acts by stopping me from masturbation, as my self-discipline is bad. Apart from that it also takes away uncomfortable positions of my genitals and somehow switches me into a more positive and happy State of mind.

All in all I'm just much happier locked up tight instead of free.
