The special technique to increase the power and intensity of your orgasm taught in this series relies on you knowing a little bit about the internal structure of your penis. It will help you understand why you are being asked to do certain things.
We are going to be concentrating on the internal muscles of the penis, in particular those intimately connected with the pleasure and function of orgasm and ejaculation called the pubococcygeus (pronounced pew-bo-kok-cye-gee-us) or ‘PC’ muscle for short.
The illustration below shows the internal structure of the male genitals. You should note a sheath of muscle running from the anus forward toward, between the legs (the perineum) the root of the scrotum. This forms part of the PC muscle.
For the more scientifically minded, the PC muscle begins at the back of the pubis and from the front part of the obturator fascia, running backward horizontally along the side of the anal canal toward the coccyx and sacrum to which if finds attachment.
In between the end of the vertebral column and the anus, the two PC muscles come together and form a thick, muscular layer lying on the raphé formed by the iliococcygei.
The greater part of this muscle is inserted into the coccyx and into the last one or two pieces of the sacrum.
In plain English what this means is that there is a sheath of muscle that runs from your anus forward in-between your legs to the base of your scrotum or balls. You may not know its there or have used it much but all that is about to change.
It’s important to remember that there are no bones or muscles in the penis itself, which is made up primarily of spongy tissue that becomes engorged with blood during arousal and erection. However, two or three inches of the penis are rooted inside the body in the PC muscle.
When you want to stop urinating in mid-flow it is this muscle you use to stop the flow of liquid through the urethra. If you want to control a bowel movement and tighten your anus, you are also tightening the PC muscle as both are interrelated. It is also the PC muscle that rapidly and rhythmically contracts when you orgasm and ejaculate, moving the semen up through the penis and out of the body. It is these rapid, involuntary muscular contractions during orgasm that produce the unique and pleasurable sensations experienced during ejaculation.
Orgasm and Ejaculation
Understanding what happens in your body when you orgasm and ejaculate will help you understand why the exercise you will learn can be so effective in improving your sexual pleasure.
When a man has sex or is masturbating, he eventually reaches a point of maximum sexual excitement and stimulation and feels himself ‘coming’, sometimes referred to as ‘the point of no return’. This is that short period when he feels ejaculation and orgasm are inevitable and cannot be stopped.
It is then that a spinal reflex causes the rapid rhythmic contractions of the PC muscle, along with contractions of muscles in or around the anal sphincter, rectum, perineum (the area between your legs bordered by your anus at the back and your scrotum at the front), urethra and prostate gland. It is these rhythmic contractions that account for the spurting action of semen during ejaculation.
At first the intervals between muscle contractions are about 0.8 seconds but these rapidly become longer and the contractions become slower with the intensity of the contractions tapering off after the first three or four initial spasms.
The word ‘orgasm’ refers specifically to these sudden and rhythmic muscular contractions in the pelvic region that release accumulated sexual tension and result in an intensely pleasurable sensation. Orgasms can vary from person to person and for each individual at different times. For some it can be an explosive rush of overwhelming sensations where all inhibitions and self-control are lost.
At other times and for other people it can be subtler and less intense experience. The varying intensities of orgasm can be due to physical factors such as fatigue, length of time between orgasms, mood, relation to your partner and the condition of the PC muscle.
Of course, orgasm is not just a pelvic event but also involves an alteration of brain wave patterns as well as the tensing of muscles in many other parts of the body. However, the chief focus of sensation for most men occurs with the intensely pleasurable contractions of the PC muscle, anal sphincter, rectum, perineum and genitals.
Much like working out your biceps can give you better definition and more upper arm strength, the PC muscle can also be exercised to improve it's strength and condition.
Because the muscle is so intimately connected to the pleasure of orgasm, toning up the PC can help you not only strengthen and better define your erections but also increase the pleasurable sensations experienced when coming.
In the next installment, we will take a closer look at the PC muscle.
