 1. It needs to be erect for you to nurture it. A man needs to have an erection regularly simply so that he can maintain the health of his penis. In order for the penis' muscle to receive a healthy amount of oxygen, it must be erect. The regular supply of oxygen protects it. If there is no health problem, a man can have an erection naturally, however during the day when the conditions do not allow this to happen, you should not be worried, because the brain has a mechanism to protect the penis. Electric currents from the brain cause an erection during sleep. This occurs during the dreaming phase of sleep, which is known as REM. It does not matter if you have an erotic dream or even if you dream about zombies, because the penis becomes hard during this sleep cycle. A healthy man has an average of 3-5 erections during a full night’s sleep, where each erection can last between 25-30 minutes.  Yes, this is probably what explains a morning erection, which is simple proof that your brain and your penis were properly working at night, exactly how they are supposed to.

There are men who cannot have an erection for emotional reasons or because of an illness. If this problem is not treated, their penis may become shorter. Without regular erections, the penis' tissues can become less flexible and shrink by about one or two centimeters. It is recommended that men who do not have regular erections seek medical advice.

 2. It is not the quantity but the quality!  For men, there is almost no connection between the size of the penis when it is relaxed and when it is erect. What is certain is that when you are in a dressing room or a bathroom, and when you see different penises around you and you begin to make comparisons to your own penis, just know that you are almost always wrong because if you are jealous of the size of a man's penis when it is relaxed, it does not necessarily mean that this is the size of his penis when it is erect. On the other hand, a man with a small penis, who you may have mocked in your own mind, could possibly have quite a large penis when it is erect. A British study discovered that in fact during an erection, the penises that are smaller when they are relaxed become much longer than the penises that are larger when they are relaxed. American sexologist, Alfred Kinsey, discovered that for 12% of men, the penis grew by a third or a little less during an erection and for 7% it doubled in sized. Therefore, there is no reason to make comparisons.

The size of the penis that can be seen is only half of its true size, because the second half is within the body. In fact, an MRI of an erect penis shows that it is like a boomerang.

For teenagers, no "normal penis size" was defined because everyone develops at a different pace. The average size for an adult penis during an erection is between 14-16 centimeters. A penis will be considered very small only when its length is less than 7.6 centimeters during an erection. If you insist on comparing, then it is important to know that there is no point in measuring the length of the penis when it is relaxed because the external temperature is very influential – when it is colder it shrinks and when it is warmer it becomes longer. For anyone still insisting on measuring… you should do so when having an erection, from the base of the penis on the side of the abdomen.

Remember that the size of the penis has no influence on a man's reproduction because that depends on the quality of the sperm (which is created in the testes) and in its normal motility. Also, the quality of the sex is not affected by the size of the penis but rather by the emotional relationship you have with your partner (being open, good communication), varying the positions and knowing the preferences of your partners.

In heterosexual relationships, a longer penis has no advantage over a shorter penis because the woman's arousal spots are in the region of the vulva and consist of the clitoris and the G-spot, which is located in the upper section of the inner vagina, close to its opening, and it is not necessary to have a long penis to reach it.

 3. Where is the penis most aroused? In a British study conducted in 2009, it was revealed that the majority of men feel most aroused in the lower portion of the tip of the penis (glans) and at the lower urethra.  After those regions, the regions that are most aroused when touched are: the upper part of the tip of the penis and its sides, the sides of the penis, the upper part of the urethra and the foreskin (for those not circumcised).

 4. The penis becomes less sensitive with age. Studies indicate that the penis becomes less sensitive with age but it is difficult to prove to what extent since the studies used different methods to arouse the penis and measure its sensitivity. Mainly, sensitivity is determined based on the intensity of the arousal required for a man to feel it. Even though they were not able to exactly determine to what extent the sensitivity decreases, starting with age 25, the sensitivity starts to decrease, with the most drastic change to the penis' sensitivity occurring between the ages of 65-75. What is mostly unclear is whether men feel the change with age? It is not certain, or at least this is what the study indicates. In cases where it is difficult to have an erection or an orgasm, it is recommended to consult with a doctor.

 5. Vibrators also work on penises. Apparently, vibrators are not only for women. They also arouse the penis and help to have an orgasm. In fact, medical vibrators are so effective that they can also help men who have injuries to their spine reach an orgasm.

 6. A circumcised penis has a lower chance of contracting diseases as opposed to a non-circumcised penis. The penis' foreskin is an incubator for bacteria to settle. In an American study conducted in Uganda, bacteria samples were taken from the penises of men who are not circumcised and from men who are circumcised. The results of the study indicate that circumcised men have less bacteria in their penis, probably because the foreskin allows for humidity and good living conditions for cultivating bacteria.

The World Health Organization (WHO) recommends circumcisions in order to reduce of chance of contracting sexually transmitted diseases and HIV/AIDS. Also, men who are circumcised are less likely to infect their sexual partners with sexually transmitted diseases and have a lower chance of having penile cancer. Nevertheless, this does not exempt any man, circumcised or not, from using a condom in order to prevent contracting sexually transmitted diseases or HIV/AIDS. Circumcision is not an excuse!

 7. The penis can break when erect. If the penis is violently bent when it is erect, it can break. Even though the penis has no bones there are blood vessels that can burst and the blood can leak out into the penis causing very painful swelling. If you are concerned that you broke your penis, then seek medical attention immediately.

 8. Every penis has its own direction. When the penis is erect, it can lean right or left or it can protrude outwards at a straight angle or it can even lean downwards. There are many differences between each man in the angle of the penis when erect and it is not a question of being healthy or not. Nevertheless, it is important to point out that if the slant of the penis is painful when erect, you should consult with your doctor.

 9. Penis Enlargement. In many cases the desire to enlarge the penis stems from psychological motives and not physical motives. Therefore, if the size of your penis bothers you, you should simultaneously seek medical consultation from a doctor and an emotional/sexual therapist, and thus receive the maximum amount of information about the possibilities of penis enlargement and the implications of the process. Most of the solutions offered on the Internet – creams, pumps, minerals, hormones – have not been proven as scientifically efficient, and most of them have been revealed to be unhealthy. There is a surgery to lengthen and/or enlarge the girth of the penis, however there is no proof that it is efficient and there is no sure proof that it improves the lifestyle of those who undergo the surgery.

 10. When the body ages, the penis also ages. Starting at the age of 30, the penis undergoes many changes. This is considered the age at which the penis is at the climax of its sexual functionality up to the onset of old age. Naturally, the appearance of the penis changes. The glans slowly loses its purplish color because there is less blood flow to it. Pubic hair thins and falls out. If one gains weight, the penis looks smaller and therefore it is recommended that men who are overweight diet and lose weight not only for medical reasons such as diabetes and heart disease, but also so they can have a safer and better sex life. The length of the penis also becomes shorter over the years and a difference of a few centimeters is noticeable in the length between ages 30-60. Somewhere around age 40, the testes also begin to shrink. As we get older, the penis is less sensitive and it may be more difficult to reach an orgasm. However, today there are drugs and treatments that can help in this situation. It is important for older men to continue to enjoy sex even if the appearance of their penis changes, because the pleasure you can give to your partner does not depend on the size of your penis at all…

In conclusion, a condom can best protect your penis and your general and sexual health. If we set aside for a moment the size of the penis and its sexual performance, it is important to remember that ultimately you can contract unwanted sexually transmitted diseases and HIV/AIDS from sex. Be your best protector and keep a condom in your pocket so that you will be ready for any situation.
