Ejaculation that got just to the point before the tip of the penis?

Hey guys and gals,

I have some multy-year experience with Mantak Chia's books, with not regular practice. However after discovering this sub I understood lots of stuff and started practicing with more discipline.

So today, after successfully stopping the urge to ejaculate at what felt like right before PONR by a small contraction if my pelvic floor (really gentle), I felt like the arousal got dissipated, though I felt the contractions of the muscles at the lower back - which were responsible for starting the ejaculation. So it felt nice, but the ejaculatory feeling was there too. And most importantly, it felt like a bit of sperm stopped right at the tip of my penis, without exiting. As my horniness calmed down, I dosed off for a micronap (so, lactase was formed in my brain I guess?)

After I woke up I continued. Then the arousal got from 2 to like 9 for less than 7 seconds, and I barely had time to relax and redirect.

I felt these muscles contract again almost instantly, with x2 force, and no chance of relaxing them, and my penis blurted out almost immediately the sperm I was feeling stopped at the tip of my penis; and then I felt the muscle at the base of my spine contracting incontrollably, until I ejaculated what felt a regular ejaculation.

Anyone has had such an experience, of stopping the ejaculation before it exited the penis? It could have been a ... semi-reverse one I guess 😆.
