Chastity and orgasm denial discussion

I’m at a loss for words. Last night was typical; my wife and I were snuggling in bed, and she went about teasing my nipples as usual, pausing and resuming whenever she pleased. Around the midway point, when she started up again, I felt a small blob-like substance travel all the way through my penis and exit. It began low down between the cleft of the buttocks and the cage, and I sensed it throughout its journey. I’ve heard others mention this happening during dreams or otherwise. Now I’m craving for it to happen once more; having been locked without release for three weeks, does the intensity increase over time? How long until my body decides to clear everything out?
