CATERGORY: DELAY EJACULATIONS

The Forces Behind Ejaculation

During ejaculation, three different branches of the nervous system trigger cascades of muscle contractions that lead to orgasm.

During sexual arousal, the brain responds to stimuli from different parts to the body (eyes, nose, ears, skin, penis) and thoughts. And makes penile skin more sensitive to touch. Since the skin covering the shaft and glans of the penis is filled with nerve endings sensitive to pressure and vibration, more touching further increases sensitivity in a positive feedback loop.

When enough stimulation trips arousal into orgasm, three ejaculatory centers deep in the brain fire off impulses that signal the body to release sperm from the testes, create semen, and initiate contractions that expel semen out of the penis along with accompanying orgasmic pleasure. |

The final expulsion is actually an involuntary reflex initiated by a group of neutrons near the base of the spinal cord with no involvement of brain input. The first few contractions are so forceful that semen can easily travel the 5 to 6 inches of the penis urethra then fly one to two feet through the air. These first 3 or 4 strong contractions are followed by several seconds of slower and weaker pulses. Typically between 2 to 5 ml of semen is ejaculated.
