Cold air, cold water, fear, anger, or anxiety can cause the penis, scrotum, and testicles to be pulled closer to the body, thereby shortening it to micropenis lengths.
Warm conditions on the other hand can cause the penis to lengthen. Although the size of the nonerect penis differs widely from one male to another, this variation is less apparent in the erect state. EvenSeinfeld weighed in on the shrinkage issue.
Some penis reference points:
1. The Kinsey Report, 1948: average length of 6.20 inches (15.25 cm) with a standard deviation of.77 inches (1.96 cm).
2. Study by Wessells et. al., 1996: average length of 5.1 inches (13.0 cm).
3. Other studies: average length of 5.7 inches (14.5 cm).
The debate over circumcision has been going back and forth for years. Some American medical experts believe that all newborn males should be circumcised. The side in favor cites the decreased rate of urinary tract infections and sexually transmitted diseases among circumcised men, and the other emphasizes the pain and stress inflicted on a baby during circumcision. Others believe that the benefits of circumcision are not great enough to justify the possible complications of the procedure. In 1999, the American Academy of Pediatrics Task Force on Circumcision found potential medical benefits of circumcision, but decided that the evidence was not strong enough to recommend routine circumcision. But, more important, back to sex.
There are several studies found in urology literature that look at the effect of male circumcision on male sexual satisfaction. These studies found conflicting answers.
The effect of male circumcision on the sexual enjoyment of the female partner was also examined in a study in theBritish Journal of Urology. The authors concluded that “women preferred vaginal intercourse with an anatomically complete penis over that with a circumcised penis.” Interestingly, the authors of the study also wrote and published a book entitledSex As Nature Intended It. They also recruited some of their volunteers for the study from an announcement in an anticircumcision newsletter. We mention this not as circumcised males but as impartial interpreters of the medical literature.
Interesting circumcision facts:
The twelfth-century physician and rabbi Moses Maimonides advocated male circumcision for its ability to curb a man’s sexual appetite.
Male circumcision was introduced into English-speaking countries in the late 1800s as a method of treating and preventing masturbation.
Male circumcision, the most commonly performed surgery in the United States, removes 33 to 50 percent of the penile skin, as well as nearly all of the penile fine-touch neuroreceptors.
Everyone has a preference.
President Clinton revealed on MTV that he preferred boxers.
Kramer onSeinfeld said, “I need the secured packaging of jockeys. My boys need a house!”
The question is whether or not there is any science behind making this decision.
It was originally thought that wearing tight underwear could lead to infertility in men as it may raise testes temperature to a point where it interferes with sperm production.
In 1998 inThe Journal of Urology, Drs. Robert Munkelwitz and Bruce R. Gilbert analyzed semen samples from ninety-seven men with fertility problems. Half of them wore briefs, the other half wore boxers. The researchers measured the men’s scrotal, internal, and skin temperatures, both while the men were wearing underwear and again when they were going commando. They found no significant differences between the two groups of men in scrotal temperature, sperm count, sperm concentration, or sperm motility.
The purpose of the scrotum is to maintain the testes at a temperature of approximately five degrees less than the rest of the body (about 93.6 degrees F). It appears as though the scrotum does its work whether you are in boxers, briefs, or free ballin’.
So you can make your own fashion choice and your sperm won’t know the difference.
An article in theAmerican Journal of Obstetrics and Gynecology in 2001 called the G-spot a sort of gynecologic UFO. Well, the authors of that article may want to start readying themselves for space travel. That is, after they read this paper from Cairo University: “The Electrovaginogram: Study of the Vaginal Electric Activity and Its Role in the Sexual Act and Disorders.” In this paper, the authors investigated the hypothesis that the vagina generates electric waves, which affect vaginal contraction during penile thrusting. They found electric waves could be recorded from the vagina. They also postulated that there was a vaginal pacemaker that seems to represent the G-spot, which is claimed to be a small area of erotic sensitivity in the vagina.
So what is this vaginal Loch Ness Monster?
The G-spot is simply a small area located on the upper wall of the vagina, toward the belly, about two to three inches from the vaginal opening. The G-spot was named in honor of Ernst Grafenberg, a German physician who, in the 1950s, wrote an article that mentioned an erotic zone on the anterior wall of the vagina that would swell during sexual stimulation.
There are various opinions on the best way to find the G-spot. Some women say that being on top during intercourse works best. Others swear by rear-entry as the best way to hit the G-spot. Some even say that because of its location, a shorter, smaller penis may actually be more effective at reaching the G-spot. A clue to its location may be that some women feel a sudden urge to urinate when their G-spot is touched — not surprising since the G-spot is located right near the urethra.
For those of you who have never heard of Kegel exercises, don’t expect to see a class offered at your gym.
Kegel exercises were originally developed as a method of controlling incontinence in women following childbirth. They’re named after Arnold Kegel, the Los Angeles doctor who promoted their development in the 1940s. The principle behind Kegel exercises is to strengthen the muscles of the pelvic floor, or the pubococcygeus muscles. These muscles run from the back to the front of your pubic bone and encircle the openings of the vagina and rectum. Strengthening them helps improve the urethra and rectal sphincter function.
These exercises are recommended for women with urinary stress incontinence, but many others do Kegel exercises for more fun reasons.
Advocates believe that there are several benefits for a woman who exercises her vagina. They claim that it makes it easier for her to reach orgasm, makes orgasms stronger or better, and makes the vagina more sensitive.
Heat is damaging to the sperm, and theoretically can affect male fertility to a certain extent. But, there is no clear scientific evidence that implicates hot tubs. There may be a temporary reduction in sperm function after a soak, and prolonged repetitive use could cause problems, but none severe enough to avoid the occasional dip.
Saunas do not appear to influence fertility either. A few studies have reported decreased sperm count or decreased sperm movement after sauna use, but in Finland, where saunas are most common, men have high sperm counts and no apparent fertility issues.
