Hi @Flip-flop.
The words orgasm and ejaculation are often treated as one and the same, for people born with a penis. I’ve come to understand them as different things that (for most) happen at close to the same time during masturbation & sex.
Add into this that people with different bodies, and expectactions, can have hugely different experiences. Some can have anorgasmic ejaculations, others orgasm without ejaculation. Some reach the point of no return (PNR) quickly, while others have delayed ejaculations, or don’t reach the PNR.
An orgasm, I would consider, is an explosion of sensations and pleasure in the mind and nervous system, while ejaculation is a more physical reflex that results in the release of ejaculate from the prostate and testes at the PNR.
I’d say for me the orgasm happens at around 98% arousal, and the ejaculation is at the 100% mark.
What you’ve described sounds like it could be an extended orgasm, or possibly a couple in series, with a ‘ruined’ ejaculation. I might be wrong. It sounds hot and intense though!
My own feeling is that the ‘ruined orgasm’ is actually not a great name for such a fun thing to do! Maybe it’s ironic? The orgasm can be prolonged and pleasurable, and even multiple while I’d say the ejaculation’s the part that’s held back, or ‘ruined’.
My own experiences of multiple orgasms have usually released pre-cum only (clear) or sometimes nothing at all, with ejaculation (cream coloured) only happening with the final orgasm.
I usually lose my erection after ejaculation, but if I can orgasm without ejaculation the fun keeps going!
The key to multiples for me seemed to come from edging and really understanding the fine levels of arousal just before the PNR, and learning to use PC muscles (these need to be in shape) and breathing techniques to hold back from ejaculating.
Hope this is helpful.
