My experience for overcoming PE would blow your guys mind, and it happened to me naturally as I was having sex with my GF.
It was Limitless, and yes you read that right.
The ability to breath deep into your ball, feel every sensations, and controling every breath as you take, making you balance out the fight/flight mode, the mode that causes you to ejaculate. And get into the whole body relaxing, the mode that keep you can having sex for as long as you want. Could see it as microcosmic as you circulate the sexual energy to your whole body.
I was applying the 4 seconds breathing rules, 4s in, 4s hold and 4s out. Keeping it nice and simple, breathing deep into your D, feel the sensation, then hold it for 4s, and release it along with all the tensions from the D, and every muscle you used to penetrate her, then repeat.
With this technique I was be able to having sex longer than normally, more than one hour and a half then decided to stop just because I want her to get home and get some sleep for her morning work at 7AM. Then she’s mad at me for not letting her orgasm lol.
It took sometime at first and after awhile you get used to it and start penetrating faster.
All of them just from the Body-Kinesthetic scripting which is insane side effect
