Taping glans for ADS vac hanger

I’ve been trying to using a vac hanger as an all day (and or all night) stretch device. It is very comfortable except for the tip of my glans. If I wear it for several hours the tip of my glans becomes irritated and chapped. In the worst case scenarios I’ve given myself blisters. I’ve tried the search button and found many posts on how to tape for short term hanging with weights. I’ve tired a couple of these methods, but the tape eventually bunches up and causes more pain that when I go without. Does anyone have a taping technique for using a vacuum clamp for long duration?

Thanks,
