Introductions discussion

Hi, here’s some context I’ve been wearing panties and sexy underwear for a couple of years. The fit shows off my package well; I’m average size but on the thinner side. I use butt plugs and have strap-on sex about once a month. This isn’t forced, we both enjoy me wearing thongs or boy shorts. full back panties work too. She enjoys dominating me anally. She loves satin and likes feeling my cock through the material; she’ll often have me wear a satin thong while taking me anally, stroking me through the fabric. We looked at several chastity devices and eventually settled on a metal cage. I’ve been locking myself up to get used to it. On Wednesday night we went out with her holding the key. The moment I was locked and saw the key hanging from her neck between her breasts, I started shaking with orgasmic energy without actually coming. I was excited but worried anyone might notice the device. she asked why they would, so off we went. I felt nervous yet thrilled all night until we got home. We headed straight to the bedroom where she brought out her toys and worked herself to an orgasm. As soon as she finished, she unlocked me and climbed on top; I lasted less than two minutes and came deep inside her. sorry for such a long background story, but my question is how do i get my wife to deny me for at least a few days or give we an orgasm in chastity. When she says she needs me to give her fulfillment.
