this is one of the best descriptions of ejaculation and emission in the male body :
Approaches to understand male orgasmic experience with ejaculation
Physiological Approach
The physiology of male orgasm includes the physical conditions and reactions during the development of sexual tension. Physiologically speaking, ejaculation can be divided into two stages (2, 3, 7): emission and ejaculation as such (4).
Emission is the expulsion of the seminal fluid released by supportive reproductive organs (prostate, seminal vesicle) through ejaculate ducts (efferent vessels of the testicle, epididymis, and vas deferens) and deposited in the prostatic urethra (2, 6, 7) due to the reflex contraction of such organs (9). Emission takes place a split second before ejaculation and is controlled by the autonomous nervous system (4). As the semen is collected in the prostatic urethra, the urethral bulb is expanded twice or thrice its normal size, anticipating the second stage. When the urethra’s striate sphincter closes it increases intra-urethral pressure associated with the sensation of imminent ejaculation (7) or «inevitable ejaculation» (4), initiating the ejaculation by pressure changes and subsequent distension of the urethra (10).
The second phase of ejaculation begins when collection of genital discharges in the prostatic urethra has ended (1). This phase includes propelling of the semen to the urethral meatus through the membranous portions and relaxation of the striate sphincter or urethra, the contraction of the smooth sphincter and the rhythmic contractions of the prostatic urethra, the penile urethra, and the muscles at the base of the penis (2, 7, 11, 12). These movements end when semen is expulsed through the urinary meatus by cyclic contractions of the last part of the penile urethra at 0.8 seconds intervals (2, 5-7, 9). Contractions are the driving force of the ejaculatory reflex, applying pressure on the base of the penis expulsing the semen in three to seven spouts (4). The internal sphincter of the urinary bladder neck remains closed so that the seminal fluid can make it to the penis (6). After the first three or four penile contractions, they begin to space out declining in intensity (5).
In the resolution phase, after ejaculating, the male enters into a refractory period, when another ejaculation is impossible. The duration of this period can range from minutes to several hours and becomes more prolonged with age and after repeated ejaculations (4, 6).
Male ejaculation and sexual pleasure: A complex relation with multiple determining factors | Ledón Llanes | Revista Sexología y Sociedad now after 20 years of edging prolonged masturbation I first understood the mechanism which is running in the male body ! it makes me horny to read this and practice edging ritual over many hours and days with multiple totally unsatisfying and ruined ejaculations ! through extreme sperm pressure and closing of valves the prostatic urethra is expanded to 3 times of its normal size ! the prostate and entire male reproductive system is suffering under this extreme conditions = BLUE BALLS ! each ruined ejaculation the male body gets more and more addicted to this practice !
He's the guy on the right side
