How Do I Do This?

I am desperate. I need any advice or words of encouragement you can offer. This is day 4 of no orgasms. Female orgasm denial is my newest fetish and obsession and it has me aroused every waking moment. In fact, even my sleeping has been inundated with visions of sex since I began my denial. I am so horny, I physically ache. My husband was unsure about this at first but now he is getting aroused by my desperation. He said that if I accidentally orgasm, that he will put a clothes pin on my clit. That sounds extremely painful yet also exciting at the same time. I’m wet all the time. I can’t focus on anything except my throbbing pussy. What can I do? Will this get easier for me? I’m ready to give up, but the arousal is exciting. It’s like I’m being held captive, but I don’t really want to escape.
