if you jerk off quick, you train yourself to blow quick. pavlovian en train ment..
if your breath is quick, and mouth breathing - which activates your sympathetic (fight flight freeze flop fawn and ejaculate ) nervous system - you are more likely to lose your shit.
if you are breathing thru your right nostril, you are in sympathetic nervous system activation, and again, more likely to cum. You can also experience ED here for this reason too.
if you are all tense, all nervous, and your pelvis floor has lots of tension, you are more prone to PE. and ED.
training yourself by stopping porn,
going on a dopamine detox ideally,
practicing semen retention, starting with holding your pc muscles, stopping your urine flow for 12 secs, starting again; do this 3x. every time you piss.
then practice getting near the PNR - point of no return - when your balls tighten, and you get super hard, and catch yourself just before ejaculation during self pleasure, the first spasm is the latest. CLEEEEENCH. this will take abs, glutes, fists, toes, teeth gritted initially, learn as soon as can to clench, then relaaaaaaax asap.
after some months you can pull out, with no leakage, and choose when to ejaculate; or just don't.
i used to ritually ejaculate every 2 weeks for 6 odd years. had so much power, magnetism, always had a harem of women i was rotating, this was after i spent 2 years not being able to control myself, after i started knocking one out quick to porn, after my first breakup at 18.
almost 2 years of not having control, and i started looking into it.
then seeing cocaine's effect, MDMA, sativa, alcohol effects on ED, for me... brewers droop was exacerbating my "cold in my extremities" - reynaulds. kidney & cardio dysfunction.
if you find the root cause(s), it's very easy to sort out. with effort.
