Male Chastity Now discussion

Mark’s gadgets are nice to me, yet their security screws don’t hold firm against anyone carrying Allen wrenches. That made me look for a padlock that could serve both the upper and lower locking points while preferably sharing one key. The master lock measuring 3/4 inch sold by Mark fits the top spot but not the bottom one (I measured another from elsewhere at exactly 3/4”, so my measurement might be off). Finding locks via their specific dimensions turns out to be trickier than expected, so I’d value it if anyone who has already located a suitable one or is good at hunting down items could share what they found.
