Penis panic ( koro in Malaysian/ Indonesian) — delusion of shrinkage of the penis and retraction into the body. This appears to be culturally conditioned and largely limited to Ghana, Sudan, China, Japan, Southeast Asia, and West Africa.

Penile measurements vary, with studies that rely on self-measurement reporting a significantly higher average size than those which rely on measurements taken by health professional. A 2015 systematic review of 15,521 men in which the subjects were measured by health professionals showed that the average length of an erect human penis is 13.12cm (5.17 inches) long, while the average circumference of an erect human penis is 11.66cm (4.59 inches).

Seminal vesicles are 2 small organs that produce semen, the fluid that sperm moves around in. They’re located below your bladder.Benson, Janette (2008). Encyclopedia of Infant and Early Childhood Development: A-F. Academic Press. p.279. ISBN 9780123704610. Circumcised penises do not have a foreskin, which means that the glans is always visible. Uncircumcised penises have a foreskin, which often covers the glans, especially when the penis is flaccid. The corpus cavernosum forms most of the penis and contains blood vessels that fill with blood to help make an erection. Carlson, Neil. (2013). Physiology of Behavior. Upper Saddle River, New Jersey: Pearson Education, Inc. Like all shapes, this one’s got some solid perks. The narrower head makes for easier entry, and a wider base provides more stimulation the deeper you go.

Uncircumcised men can also develop phimosis, where the foreskin cannot retract over the hood of the glans. This can lead to irritation and infection. People with the condition generally require medical circumcision.Snell RS. The perineum. In: Snell RS, ed. Clinical Anatomy. Philadelphia, Pa: Lippincott Williams & Wilkins; 2004:430–431.

The anus has lots of sensitive nerve endings, so some people experience sexual pleasure from anal stimulation. Cold glans syndrome is a condition marked by the persistent inability of the glans penis to maintain an erect state during sexual arousal, potentially leading to reduced sensitivity and erection difficulties.

An erection is the stiffening expansion and orthogonal reorientation of the penis, which occurs during sexual arousal. Erections can occur in non-sexual situations; spontaneous non-sexual erections frequently occur during adolescence and sleep. In its flaccid state the penis is smaller, gives to pressure, and the glans is covered by the foreskin. In its fully erect state, the shaft becomes rigid and the glans becomes engorged but not rigid. An erect penis may be straight or curved and may point at an upward angle, a downward angle, or straight ahead. As of 2015 [update], the average erect human penis is 13.12cm (5.17in) long and has a circumference of 11.66cm (4.59in). [2] [3] Neither age nor size of the flaccid penis accurately predicts erectile length. There are several common body modifications to the penis, including circumcision and piercings.David M.

Other practices that alter the penis are also performed, although they are rare in Western societies without a diagnosed medical condition. Apart from penectomy, perhaps the most radical of these is subincision, in which the urethra is split along the underside of the penis. Subincision originated among Australian Aborigines, although it is now done by some in the U.S. and Europe.

If you’re able to get erections, by all means do. Masturbate, have sex with a partner, or do anything else that gets you hard — whether you climax or not. Sex dreams and morning wood count.

It tends not to share the common blue tint with a vein however. It can be felt as a hardened lump or "vein" even when the penis is flaccid, and is even more prominent during an erection. It is considered a benign physical condition. It is fairly common and can follow a particularly vigorous sexual activity for men, and tends to go away if given rest and more gentle care, for example by use of lubricants.Lynchings in Congo as penis theft panic hits capital".

This led to a [medical] consensus that male circumcision should be a priority for HIV prevention in countries and regions with heterosexual epidemics and high HIV and low male circumcision prevalence. Priapism is a painful and potentially harmful medical condition in which the erect penis does not return to its flaccid state. Priapism lasting over four hours is a medical emergency. The causative mechanisms are poorly understood but involve complex neurological and vascular factors. Potential complications include ischaemia, thrombosis, and impotence. In serious cases the condition may result in gangrene, which may result in amputation. However, that is usually only the case if the organ is broke out and injured because of it. The condition has been associated with a variety of drugs including prostaglandin. Contrary to common knowledge, sildenafil (Viagra) will not cause it. [57]
