Hormones are secreted which lead to a higher volume of blood flowing into the spongy tissue columns of the penis than flow out. The penis erects this way; sometimes the penis will leak fluid and/or sperm before the orgasm, regularly referred to as pre-ejaculate or “pre-cum.” The scrotum and dartos muscle draw both testicles up toward the pubic bone, pressing the epididymis upward. As stimulation continues, the swelling and fluid production continues to increase. The plateau continues until just before the orgasm. When orgasm begins for males, the penis is most erect. Males reach a point of no return in their orgasms; females do not. The ejaculation of sperm and fluids will continue in males, regardless of continued or interrupted stimulation.
