Chastity and orgasm denial discussion

I’m secured in the Jailbird cage by Mature Metal, which is pictured in my avatar. It’s surprisingly cozy. Occasionally, when I settle into a seat and cross my legs at the thigh level, I feel one or two ‘twinges’, prompting me to quickly uncross them. Has anyone else experienced this? Specifically, where just wearing the contraption triggered an orgasm (or nearly so). We’re talking hands-free here; it was purely due to having the device on.
