Chastity and orgasm denial discussion

Hi all. My lovely lady friend is putting me into enforced chastity soon. (I’m not sure if I should be scared or excited because it’s my first time being locked up by someone else.) She knows that given enough time, I can pick the current masterlock padlocks on my belt, so she wants me to find a lock that either cannot be picked at all or is extremely hard for a newbie like me to open with just a paperclip. After doing some research, I found some ABUS locks that are supposed to do exactly that. They’ll keep me locked and frustrated for a month (at least). Does anyone here have experience with these specific models?
