There are few, but these below are biggest ones. And the most biggest ones are in Bold: Training our bodies to ejaculate quickly by rushing to finish (or reach the edge of orgasm) faster during masturbation cause premature ejaculation (which is what everybody basically does when using porn, so it would not be incorrect to say that porn causes PE) Training our nervous system to get aroused quickly causes premature ejaculation (here it would also not be incorrect to say that porn is a cause because it is unnatural, supernormal stimulus) Ejaculating too often (more than 3 times a week is too often and that's generous, ejaculating 1 time a week or less is even better) cause premature ejaculation Kegel (PC muscle) exercises cause premature ejaculation (because many people are flexing the wrong muscle, what they are actually flexing is BC not PC) Flexing BC muscle during sex to get erection faster cause premature ejaculation Not keeping BC muscle all the time relaxed during sex cause premature ejaculation Anal prostate stimulation cause premature ejaculation And then of course there are mental things that cause premature ejaculation (such as performance anxiety) and other physical things (such as brain trauma, genital injury, hormone imbalance and other diseases) that cause premature ejaculation. But the ones mentioned above are the most common causes of premature ejaculation. And the biggest reason of them all is flexing BC muscle during sex/masturbation and not keeping it relaxed. How to treat premature ejaculation? Masturbate slowly so you reach edge slowly. It's not just stop and go technique when you reach edge fast and then stop and then go again and reach edge fast. You actually have to train your body to reach edges slowly. Train yourself to get aroused slowly. There are arousal control exercises out there that are designed for this. These exercises usually focus on visualization and mindfulness meditations combined with controlled breathing techniques. It all is designed to slow down your heart rate and relax all of your body's muscles to prevent accumulation of muscular and nervous system tension. Stop ejaculating more than 3 times a week (preferably no more than once a week or less). Preferably don't ejaculate at all while you are healing, go on Hard Mode Stop doing kegel exercises the wrong way. Find the right muscle Stop flexing your BC muscle during sex to get faster erection or to increase the strength of erection Do reverse-kegels to reverse damage that doing normal kagels (if you did them wrong by flexing BC muscle instead of PC muscle) has done to you Learn to use reverse-kegels to stop involuntary "kegels" (BC muscle contractions) during sex that you have programmed your body to do automatically Locate your real PC muscle and do proper kegels Stop (or at the very least drastically decrease the amount) all anal stimulation. How to learn difference from PC and BC muscle? Many people actually increase their premature ejaculation by doing kegels the wrong way. Because the basic guide for locating the proper muscle to flex is stopping flow of urine. The problem is that BC muscle stops the flow just as PC does. And for most people they naturally use BC muscle to stop urine, they barely ever flex PC muscle. So they mistaken the two. Another reason for confusion is that BC muscle is the right muscle to train for women to get stronger orgasm and bladder control (it works for this reason, but for men it also causes PE as a side effect, so it should be only female specific genital exercise, sinse they don't have to worry about PE). It is also used for men with delayed ejaculation (these guys don't have to worry about PE so it works for them). But the guidelines for women are wrongly translated for men and guidelines for people with DE are wrongly used for people with PE. So these are two reasons people often mistake the two. Basically BC muscle is under your penis (between anus and testicles). It's the one that stimulates your prostate if you flex it. It contracts during orgasm. It's the one that if flexed tightly during orgasm can cause retrograde ejaculation. It's the one that can speed up orgasm if flexed and held while you are stimulated. It's the wrong one. PC muscle is attached to your tail bone. It is located behind your anus. Almost at your lover back. It goes down deep under your pubic bone at the front part of your body too. For exercises of it however we should focus on back. When you flex it it can stop ejaculation but it can not speed up orgasm. It also usually does not contracts (for most people) during orgasm. While flexed during ejaculation with full force it will not cause retrograde ejaculation. If anything it will either stop the orgasm completely or you will have a real dry orgasm without sperm going in bladder. This is the one you wanna train during "kegel" exercises. There is a diagram (click if you are not triggered by medical drawings of genital anatomy). This is the BC muscle (the wrong one you want to train yourself to keep relaxed at all times): Spoiler: BC mucle - medical anatomical drawing of a penis This is the real PC muscle; the one you want to train (the other in red below it is the BC muscle): Spoiler: PC muscle - medical anatomical drawing of gentials So how should it feel when flexing it? Basically it should feel like you are flexing your not your perineum but your tailbone muscle. The muscle behind your anus almost at your lower back. Your butt cheeks should move a little when you isolate it (but not too much, don't actually flex your glutes) and your BC muscle should be relaxed. While if you would flex your BC muscle your glutes would not move at all. That's it guys. I tell you. This is the biggest reason why men have premature ejaculation. They ejaculate too often and mainly they have this BC muscle too flexed all the time (get orgasm faster, get erection faster, get it harder and stupid articles on internet teaching how to do kegels wrong) up to a point it does it automatically during genital stimulation. This reflex needs to eb eliminated by reverse-kegels. And habit should be eliminated too. Then just flex your tail bone muscle instead and you won't have premature ejaculation. For all those people who have premature ejaculation and do PC exercises (kegels) and it is not working for PE, you have just been exercising / flexing the wrong muscle! It's really super simple!
