I guess I may have stumbled upon something that helps tremendously with vac hangers..
That is that what creates the blisters etc is air space, so what I do is squirt some Alow vera jel into the tip of my vac hanger, then when I
Squish the head of my dick in their all the air comes out then roll down the sleeve and now I have zero air space for a blister to form in.
Let me know what you guys think?
