There isn't anything in "Male Orgasm: 13 FAQs..." from Healthline that I haven't already posted about at some point along the way.
The article reminds us to pay attention to parts other than the cock. The balls, the nipples, the prostate, and other erogenous zones, for example. Back to the prostate for The Male G-Spot - it can be stimulated externally; a finger, a tongue, or a vibrator along the perineum can provide all sorts of stimulus to trigger an orgasm.
For more intense orgasms, do those Kegels.
They not only help you learn to control when you cum - they help you build a better boner.
And take your time to build to orgasm. You can edge whether you're with someone or alone. Reaching the peak and staying there as long as you can - or as long as you desire - by changing the stimulation.
Alone? Switch hands.
With someone? Switch to frot.
The idea is to enjoy yourself. To learn to control when you cum.
So you shoot when you're ready.
