So I'm interested in doing some Male chastity play, but not for kink/sexual reasons.

Because of my adhd/depression combo I have a really hard time not masturbating's when I wake up or before bed, and coupled with some sensitivity issues, it makes it really hard to perform with partners who want condoms. I'm also newly poly and interested in group stuff, so in general I just want a higher drive and more sensitivity while wearing a rubber.. so my thought was to self cage between partners (which happens 2-3x a week) hoping the decrease in playing with myself drive better outcomes.

However I'm afraid of how it will impact my junk. I don't want it to shrink because of being caged or lack of erections. Does anyone have experience with frequent short term cagings and how they impact the function of the penis?
