Chastity and orgasm denial discussion

I wanted to share that I’m secured in a Steelworxx Steel heart cage with the PA bar fixed and a custom-cut opening for urination. My question is this: Typically, I sit down when I pee. The other day, while sitting, I gave the integrated lock tube a little shake after finishing up, just like usual, and semen came out. The PA adjustment against its posts does feel somewhat pleasant—just barely enough to notice—but not quite stimulating on its own since it hardly shifts. However, this time was different. I wasn’t turned on or stimulated at all; what flowed out wasn’t pre-cum either but real semen. I didn’t have an orgasm and the emission caught me completely off guard. Given that my last release had been more than a week prior to this incident, it seems significant. Has anyone else dealt with this? Is it the same phenomenon referred to as “drip” in discussions here? Previously, I understood dripping to be pre-cum resulting from full balls and pent-up frustration.
