If a man is ready for ejaculation, his body is undergoing numerous events.
You will see the penis's head grow and your head may change in purple color. Cowper's gland is sifted "pre-cum" fluid that leaks from its urethra. They move toward the bodies of the testicles and their size will increase. There may also be body lines, muscle tension, heart rate, and rising blood pressure.
Before ejaculation you will feel the contraction in your iron deferens, seminar, and prostate (ejaculated) to collect in a pool on your penis. You will feel a "tickling" feeling. When you are ready for ejaculation, you will feel "puffed" around the urethra.
Ejaculation leaves about a mile away as a city bus, about 28 miles per hour. But it can reach 43 miles per hour, depending on the last time it came. (All Fun and Games until someone loses their eyes!)
Once ejaculated, his skull and heres return to their normal size. You will receive a general feeling of relaxation and experience a refractory period (where you can physically not get a new erection). This time may take a few minutes and for a longer period of time.
Sex Tip: Unless there is a point of return, you can prevent severe (but very cautiously) crushing ejaculation from the tip of the penis
