Hi all, I have the nano or nub version.. not sure which.. it's a great fit for use when I'm soft.. in only and 2.5cm when soft but when I get erect during play with my wife the tube will often be pushed off my penis and I escape much to my wife's disappointment. Is there anyway to avoid that happening? Would a longer tube help? I'm guessing a prince Albert piercing would but I'm not even sure where I'd get one in Ireland. Thanks m
