Not a man, but have edged men before. If its your first time trying then I would suggest removing all other stimulus initially - one of the best things about edging is exploring and getting to know your body. Focus on what you’re feeling as you get to that stage in between pleasure and orgasm and how your body responds when you stop. Once you’ve done it a few times, you could then introduce porn/toys if you wish.
I’ve found it works best when stopping as close to possible as when you’re about to orgasm so try and really push yourself to your max - this may take some practice (and self control) when doing it solo, and so please don’t be disappointed if it doesn’t work out first few tries - it’s all about trial and error! I usually go to point of just before orgasm, wait about 30 seconds (ish - depends on person) before starting again, then repeat several times until on the brink of explosion and allow the orgasm
Some people don’t require stopping at all and just need to slow, others need a few seconds, others need a good 30 seconds before starting again so this will be down to what feels right for you.
Most importantly, enjoy it and have fun!
