Hello everyone! As some might have read already, I own a silicon birdlocked for over a year now, and my Mistress/girlfriend locks me up from times to times, but it never exceeded 5-6 days without any kind of release. For the first time, I got locked 13 days in a row, and I started seeing some rashes on my penis... Mistress unlocked me and what we saw didn't really make us happy... Lot of "burned" skin, rashes, little wounds... We're assuming it's due to friction with the silicon: Mistress is a lot into teasing me while I'm locked, and those wannabe boners don't help much I guess. The main problem is: Mistress wanted to go for a month, maybe longer, and as she doesn't want to damage me, and she wants to play with me as soon as she frees me, it's not really possible anymore with the birdlocked. We are thinking of switching to steel, but are unsure of which model/design to take. One particularity of my penis: lots of skin (was also sometimes problematic with the birdlocked), tiny when flaccid, but grows considerably. Other particularity: we live in Colombia, and we haven't found yet a nice place to purchase such material, so we'll almost have to do only with amazon.com... If anybody with experience in long term chastity can share any insight with us, it would be sooo very nice!! Is steel a good idea? Open or closed cage? Dimensions? Model? Handle the load of skin? thanks in advance to all of you!!
