I know that this is an old thread and no one has commented in a couple of years, but I was intrigued by the following comments:
(")she had several rings in lips and I decided to put tiny padlocks joining her lips...as I closed her lips, one lock at a time, I inserted a 24fr. cath in her urethra...when I finished locking her up, she told me that this was the most profoundly erotic situation she had ever experienced...there were so many emotions at play...humiliation, knowing her twat was out of commission...knowing that for the entire weekend, all sexual play would focus on her anus…(")I got a major rush reading that, I really want to try that next! Thanks for validating my recent thoughts.
and
Now I want my labia pierced an locked also It sounds like such a turn on to be that controlled.
Well, I myself was aroused by these ladies' descriptions of being turned on by voluntarily having someone enforce their vaginal chastity with small locks through their labia. Of course, according to advice elsewhere, these locks should be stainless steel so they don't rust, and through piercings of the outer labia rather than the inner, and I think a row of locks rather than just one, so there would probably be more equal distribution of the weight of the hardware pulling on the skin so that the skin does not get stretched unevenly.
Anyway, I decided to look up some images of this particular type of piercing. It turns out there is an entire tumblr page dedicated to the practice/fetish. It emphasizes the fantasy of women choosing to be denied vaginal penetration, in order to train themselves to orgasm from anal penetration: http://vaginalchastity.tumblr.com . Anyone interested enough to view that tumblr's pictures and captions that explore this fantasy will find various types of exotic chastity piercings of the vulva, and even the somewhat conventionally designed belts being worn. Some of the piercing jewelry/ arrangement of locks look better than others, but I'm sure this is subjective. I was disappointed not to see the following picture, however, which in my opinion is the best looking female chastity piercing jewelry I found when this thread inspired me to look them up- the design of this one seems to have a rare combination of some elegant simplicity and a pretty wild visual effect all at once (I will post a few links to it in case the image is taken down at any of them):
