let me bring this thread back on track... who wears the, uhhh... indispensable & 'next best thing' apparatus? 
Honestly, neither me nor most of my partners have had much interest in that sort of apparatus. I'm not sure if it's a real life thing that a lot of women are actually into, or if it's just an idea that has propagated through a fetishized view of girl-on-girl sex as presented in pornography intended for a male audience.
