Chastity and orgasm denial discussion

Hi everyone, I’m fairly new to this hobby and to the forum itself, so hello! I’ve been observing this area for a considerable time now and am quite captivated by it. My plan is to lock myself in the belt and hide the key somewhere that only allows access once a week on Thursday mornings. During those seven days I won’t be able to get back inside because it will remain shut, so expect me squirming and pleading for anything! How exciting! My main worry is whether I can handle it. As mentioned, I’m totally new here; plus, I masturbate daily, sometimes double sessions, so maybe I’ve set the bar a bit high. Also, does anyone have solid recommendations on which device to choose as a beginner? And, do any devices completely stop blood flow rushing to my penis? The idea of being entirely limp really turns me on, haha. Please share your thoughts!:)
