Chastity and orgasm denial discussion

I’ve been lurking here for a while and this is my first genuine post. Has anyone else felt numbness after using a wand while kept locked up? I’m currently wearing a Holy Trainer V2 and was told to use a wand (Doxy) until I reached climax. Because I stayed hard, my urethra got compressed, so when I finally came it felt more like an O that had been ‘thumbed’ out of shape. Not long after that, I noticed numbness down there which lasted for at least an hour or so. Has anyone else gone through this? I haven’t really used vibrators before, so I’m not sure if this is typical? I’d greatly appreciate any help or advice. Jx
