Base Modification
I know this string seems to jump between issues in comfort for the belt ring for a Phallosan and comfort for a more traditional base to a slide type extender. I happened upon something that may help avoid ball burn for a typical base to an extender.
It is really simple, but like most things, only slowly dawns. I have a few Velseal base gaskets from Pumptoys tubes. I wondered whether the base to my extender may slide into the Velseal gasket…and it does! That soft cushion seems to be an answer to avoiding ball burn from the hard plastic base ring.
