Alright I used to have this issue a few years back. I cured it though. Here's how I did it:

I took deep breathes.

Breath in for 5, hold for 5, breath out for 5, hold for 5. Box breathes they're called. It keeps your excitement at a 7 instead of a 9 (where it usually is).

Stop watching porn and maturbating so much as well. That's a big part of the issue. When you masturbate, the goal is to ejaculate quickly. When you have sex the goal is to dominate- longer the better.

Think about baseball. And lift.

It's all in your head, brother. I used to have a similar issue, but not quite as extreme. Once I got over the anxiety of the possibility of it happening, and just start enjoying sex, it became a non-issue.

Edit: Btw, your English is pretty great.

This is an atypical answer. But get your hands on a medication called Paxil for depression. Take about 20 Mg. It'll take you like 2 hrs to cum if at all.

I'm not sure about these 'give up porn' answers. Personally, when I go nofap I actually am MUCH easier to orgasm with a girl.

Now, if OP had erectile dysfunction, I would 100% agree that porn was the first thing he needs to give up for atleast 90 days.

But in this case, porn and masturbation is often known to make guys take forever to orgasm from blowjobs or regular sex because the tightness and tempo is just not the same as doing it yourself.

The most easy answer to all this is to do it yourself an hour or two BEFORE seeing your GF.. Odds are you wont then go instantly again just from mild contact.

Have a medical background. If it really concerns you, take an SSRI (antidepressant). Very common S.E of this class of drug. Note that there are other S.E, please consult your health professional before............ usual shitty disclaimer

Just try again a couple minutes after man. I used to have some serious PME, wanna know what fixed it?

Boning the girl 10 times in one day. By number 8 I had to try cum so hard it hurt.

It's all confidence and experience man. If u bust early, just laugh, say oops, and try again a few min later

I watch porn and jerk off 2-3 times a day on average and i last so long in bed sometimes i get physically tired before i can even cum. Here's the key, if you don't want to stop watching porn like most people suggest: jerk it, get close to cumming, and stop until u calm down a little, then continue. If you can make jerk off sessions last 45 minutes, then you'll cum in 45 minutes.

Stop porn ?

I wish I had this problem. It takes me FOREVER to cum during sex. Stopping porn helps, but it's still not a fun issue to have.

I also strugled with PE for as much as I can remember. What helped me was learning to be relaxed and not care much about how long I last. Magically when i stopped caring I last longer. Also I would recommend you cutting porn and masturbation. Even if you masturbate try to not cum too quickly and train yourself to be in control.

You could practice with edging

When the fuck will people learn to use the search function before posting... Go to the main sub and search.

Do you even lift bro? or run?

Work on your cardio, and drink plenty of water before the act. Plenty, like one bottle.
