Holy Trainer V3 redness under cage and soreness after out

i experience a bit of the same. Now wearing the Holy Trainer V3 for almnost three weeks, and usually i wake at night because of skin hurting. i then move the basering a bit to give the skin some fresh air, and that helps. So i think your diagnosis is right, lack of air.
Good luck!

 

So it is also a matter of time. Good to hear it disappeared. Read some of other forum posts: skin moving under the ring gets irritated in the beginning, giving rise to all kind of 'problems'. These disappear usually after 'just' a few weeks.

 

In my personal experience irritation along the glans was caused by not making sure things were clean and dry after bathroom visits. Now I make sure everything is dry with Q-tip.
[Edit: the fit is good I still sometimes get misaligned or ave some turtling while wearing my cage.]

After prolonged (like 2-3 days) wearing I do get irritation on my shaft that looks like eczema so I am in the habit of removing my cage once a day for hygiene just to clean out the cage and make sure my penis is clean, dry, and apply some lotion to the affected area. I’ll let it sit out and get some air for about 45 minutes before going back in. No touching tho ():^}
