Chastity and orgasm denial discussion

I’ve always craved something sturdier than the contraption I’m currently experimenting with, plus my physique tends to turn down piercings. To tackle both issues, I was considering getting a full belt, specifically one from Locked in Steel. However, a possible complication just crossed my mind: I have large thighs that often rub together near the top. Could this create an issue when wearing a full belt? If it does, anyone else have suggestions? It needs to be reasonably escape proof (I’ve got a friend who promised to keep a spare key safe in case S_’s copy gets lost or broken), and I prefer not using a piercing. The current unlocked status is quite annoying. After years of dreaming about this, I finally get to turn that dream into reality for three months. Thanks ahead of time for any guidance. Hoss
