Some useful facts that might teach you a thing or two about the penis:
On entering puberty, the testicles will begin to develop and the genitalia will grow. The penis begins to grow between the ages of as early as 10 or as late as age 15. Growth is usually complete by age 18–21. During the process, pubic hair grows above and around the penis.
It’s actually nice that hair doesn’t grow directly on the penis, I wouldn’t want to shave that ;)
An erection is the stiffening and rising of the penis, which occurs during sexual arousal, though it can also happen in non-sexual situations. The primary physiological mechanism that brings about erection is the autonomic dilation of arteries supplying blood to the penis, which allows more blood to fill the three spongy erectile tissue chambers in the penis, causing it to lengthen and stiffen. The now-engorged erectile tissue presses against and constricts the veins that carry blood away from the penis. More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at this equilibrium.
Erection facilitates sexual intercourse though it is not essential for various other sexual activities.
Well I wonder what other kinds of sexual activities there is referred to :o
Ejaculation is the ejecting of semen from the penis, and is usually accompanied by orgasm. A series of muscular contractions delivers semen, containing male gametes known as sperm cells or spermatozoa, from the penis (and into the vagina, if for reproductive intention via sexual intercourse). It is usually the result of sexual stimulation, which may include prostate stimulation. Rarely, it is due to prostatic disease. Ejaculation may occur spontaneously during sleep (a nocturnal emission or “wet dream”). Anejaculation is the condition of being unable to ejaculate. Well I guess you save a lot of money on toilet paper then :D
Ejaculation has two phases: emission and ejaculation proper. The emission phase of the ejaculatory reflex is under control of the sympathetic nervous system, while the ejaculatory phase is under control of a spinal reflex at the level of the spinal nerves via the pudendal nerve (somatic nerve in the pelvic region). A refractory period succeeds the ejaculation, and sexual stimulation precedes it.
So this was basically some pure facts about how the penis works for those of you interested, and of course a little remember to those of you 15 year olds who’s penis hasn’t started growing yet, you probably should begin to take some action ;)
