What Drives Men to Deny Their Cum?

I am fairly confident this topic has come up before many times, yet instead of digging through an old thread I prefer to open a fresh one. So, here is my question: what compels a man to want cumm denial? I certainly feel that pull myself. But I wonder about the root cause. Orgasms are delightful! Sure, they use up your energy temporarily, but it comes back. What makes you choose this path for yourself? Is there some hidden self-loathing involved? Or is it a subconscious sexual frustration showing up in this specific way? I know there are many reasons behind this, and I would love to read about them so I can reflect on my own motivations. At first glance, giving up such an essential pleasure seems strange, to say the least. How do you explain your craving for chastity or denial to a friend who doesn’t get it? Locknload
