I used two hair ties. They're a bit big to work as cock rings so I tied a knot in one. I put the other around my balls and base of my cock.
Then I put the knotted one mid shaft while covered then pulled it down to retract. I tucked the knot under the other tie and it's staying put nicely
Nice! I have been thinking about something like that but made of 2 cock rings :)
I may try it.
Do these keep the skin at the base when soft?
Not for me. I'm such a grower I can only stay retracted while soft with tape, so far. I just used it to stay back and rub the head with lube for a crazy cumshot
