While this is slang English, it is not considered profanity.

Root of the penis: Invisible part of the penis. It reaches near the anus and contains the bulb of the penis and the crus of the penis. The crus of the penis is attached to the pubic bone. Orgasms aren’t the be-all and end-all of partnered sex, but having the upward curve provides an advantage by making it easier to stimulate the G-spot, A-spot, and prostate. Peyronie’s disease can also be due to a rupture in the penis, known as a penile fracture. Genetic factors may also contribute to the development of this condition. If you have partnered sex, use a barrier and get tested for sexually transmitted infections (STIs) as often as is recommended. Your partner(s) should (ideally) do the same. todger - Definition, meaning & more - Collins Dictionary". Archived from the original on 7 August 2016 . Retrieved 16 January 2017.

What are the external parts?

Your penis and scrotum are the two parts of the male (or what’s typically called male) external sex anatomy (outside your body). Since the oldest cultures the penis has assumed a strong importance as a symbol of fertility used also in religious ceremonies to celebrate and (people hoped) to improve the reproductive capacity of men and beasts. For example, in Roman paganism, the god Priapus is characterized by a huge penis. In some places in Japan and South Korea, there are special days and public events to celebrate the penis. When an erect penis is shown in art or in cultural events, it is often called a phallus. In some religions, babies and young boys have their foreskins cut off. This is expected in Islam and Judaism. [20] [21] It is not required according to Christianity. Among Christians in the United States, it is more common among Protestants than among Catholics. In the United States, circumcision is less common among boys and men whose families came from Mexico, who are usually Catholic. In Judaism, infant males are required to have their foreskin removed as a sign of the covenant (ancient promise) made with God.

However, abnormal penile curvature can sometimes be a symptom of Peyronie’s disease. One review lists the following as possible symptoms: Chen, J (1 December 2000). "Predicting penile size during erection". Magyar Traumatologia, Orthopaedia Es Helyreallito Sebeszet. 19 (2): 146–151. PMID 6836. The penile raphe is the visible ridge between the lateral halves of the penis, found on the ventral or underside of the penis, running from the meatus (opening of the urethra) and continuing as the perineal raphe across the scrotum and the perineum (area between scrotum and anus). [9]Additionally, some people may have multiple kinds of curvature. For instance, some penises may curve to the left and upwards. The shaft of your penis extends from the tip to where it connects to your lower belly. It looks like a tube. Your urethra is inside the shaft. Patel, Manish; Atala, Anthony (2011-12-29).
