Safe removal of vacuum hanger

The other day I successfully made my own vacuum hanger based on this model My homemade vac hanger. .

It is extremely comfortable.

However I’m having a problem removing the hanger from my dick. I can stretch the glove to get it on to my dick, but with my dick inside it, I can’t seem to stretch the glove finger in a way that lets me get my dick out without it being painful. I ended up having to cut the glove finger down the side to remove it. I’ve tried rolling it like a condom like I read in another thread, but can’t seem to get that to work.

Please help.
