Much as the question of studies could go back and forth for ever, I have another question. @shadowman6 also mentioned being locked into permanent chastity. Personally I would have thought that was a bigger problem. We have so many stories of guys being locked for varying lengths of time, however the nature of being locked differs for many. I class being locked as 24/7 therefore there will be no one who is locked by me who will be locked for much more than 3-4 weeks without the device being taken off for safety and hygiene reasons and to check for abrasions. Others class being locked as through the day only, others still are only locked when not at work etc etc. Is being locked into permanent chastity a realistic possibility?
