Without a shaft, there would be nothing to erect for his erection. The shaft contains three columns of spongy erectile tissue; two are called corpora cavernosa, and the third, which wraps around the urethra, is the corpora spongiosum. The tissue is interlaced by a network of arteries that, when aroused, fill up with blood, creating a sight that most women are very familiar with: the raging hard-on. After ejaculation, dorsal veins drain the blood out of his penis (and hopefully send it back to his brain).
Indications/Contraindications
As the largest area of his penis, his shaft offers a ton of fun to be had. Wrap your hands around it and stroke, wrap your lips around it and lick and suck, wrap your breasts around it and titty-fuck, and of course wrap your legs around it and ride. Or make fast little licks on the underside of the shaftsideways, instead of up and down.
The base of the shaft begins inside his body, underneath the testicles. You can access this part of his shaft by pressing your forefinger or hand, lengthwise, to the center of his scrotum. Use slow, careful pressure to separate the testicles. Gently rub back and forth until you get to the base of the scrotum, where you will indirectly make contact with the hidden bottom of his shaft. If he likes it, continue the massage.
Much like the interior of your vaginal canal (as opposed to your labia and clitoris), the shaft of your mans penis is very responsive to pressure. Stimulating the head of his cock and surrounding areas with your tongue while keeping a firm or pulsating grip on his shaft may be just what the doctor ordered.
Its hard to go wrong with the shaft, but unless your guy is into penile pain, dont bite, dont pull on it like a tug rope, and please dont give him any Indian rug burns.
GLANS PENIS
Where to Find It
Glans penis is the scientific word for his little head (as opposed to his big head, which is where he presumably keeps his brain). Its the helmet that sits atop the shaft, and it houses a great number of nerve endings.
Its Purpose
Among other unusual attributeslike fully opposable thumbs, an inexplicable love for televised sports, and (compared to other primates) relatively hair-free skinhuman males are the only species who have a little head below their belts. This has caused scientists to wonder about the evolutionary purpose of this bulbous addition to his shaft. The unique mushroom shape, aside from being integral to your pleasure, has been postulated to serve an important evolutionary purpose that increases a mans potential for creating offspring.
Indications/Contraindications
Second only to the frenulum, 26 percent of our male survey takers reported that stimulation of the penis head was the most stimulating. Because of the high concentration of nerve endings and the consequent pleasure principle, the glans penis has been compared to the highly sensitive clitoris. In fact, the two develop from the same tissue in the womb. Now that you can empathize with this sensitive spot, you understand the importance of lavishing it with attention. Try licking it like an ice cream cone and use generous flicks of your tongue. Suck it like a lollipop, or treat it like a pleasurable frosting spatula by taking his shaft in your hand and using the glans to spread the juices of your slick vaginal lips or to stimulate your clit.
Use common sense. Just as you wouldnt want him to rub your clit raw, treat him the same by keeping your touch slippery and soft.
CORONA
Where to Find It
No, were not talking about a refreshing bottle of beer garnished with a slice of lime. Corona is Spanish for crown, and it describes that little ridge of flesh that separates the head of his cock from the shaft.
Its Purpose
Some scientists conjecture that the corona (or coronal ridge), aside from making his penis look like royalty, also serves as a semen displacement device. In 2003, a team of psychologists from the State University of New York hypothesized that the corona is shaped specifically so that it can scrape other mens semen out of a womans vaginal canal, by way of vigorous thrusting. The purpose is to eliminate genetic competition.
To test this hypothesis, the team used a fake pussy, of the type found at your local sex store, and three dildos, one with a large coronal ridge, another with a smaller ridge, and a third without any ridge at all. They filled the fake vagina with the semen-alternative (flour and water) and then, using each phallus in turn, recreated a thrusting motion, similar to the one your guy treats you to during a hot round of coitus. The result? Both dildos with the coronal ridges displaced 91 percent of the semen, while the headless toy only displaced 35 percent of the gunk. They also found that the deeper the thrust, the more semen was displaced.
Think about the possible implications of this study! It could indicate that men have evolved to compete for reproduction rights with women who are, by nature, not monogamous. This could support the idea that humans are not wired for monogamy at all. (Oh behave, you little trollops!)
Indications/Contraindications
As a part of his glans, the flesh around the corona is very sensitive to pleasure. With sensitivity to pleasure comes sensitivity to pain. Handle with care.
