Four tricks to effectively delay ejaculation

　　male climax ejaculation , including the entire urethra inside the penis, shrinks forward. At first it was once every 0.8 seconds, and then weakened after three or four times. At this time, the testicles, vas deferens, epididymis, seminal vesicles, and prostate also contract, and ejaculation occurs.

　　Ejaculation can be divided into two stages. The first stage is the contraction and forward movement of the above-mentioned organs, allowing the semen to enter the urethra in the prostate area. At this time, the sphincter at the bladder outlet is tightly locked to prevent semen from flowing back into the bladder. The second stage is when the semen is discharged forward to the urethral opening. Therefore, ejaculation is an involuntary reaction that "once initiated, is inevitable" and cannot be stopped.

　　If you continue to strengthen the stimulation, you will enter the second stage. At this time, the muscles located at the base of the penis contract at the same time as the muscles hanging the testicles (testicle lift muscles). Due to the strong propulsive force, the semen is released in an instant.
