But that envelope gets thin and rigid, and the penis becomes erect, and unfortunately, highly breakable.

After placing a flaccid or semi-erect one in a tight opening, a guy might not be able to get it out after it becomes erect due to the thrill of the act.

As I hold it in my hand, Elist explains that as the penis becomes erect, the Penuma opens up—a little like the doors of a Tesla Model X. Not only did this hot dog bun-like design solve the urethra snag (the FDA cleared his patented device in 143), it also enabled the device to move with the penis's countless ups and downs.

H. melanostictus may grow to a height spreads horizontally and becomes erect at the end of the branches.

During its waking hours, it remains hidden beneath a skin receptacle, until it becomes erect and it projects outside in a rostral direction.

During these greeting ceremonies, the penis or pseudo-penis often becomes erect, in both males and females. Erection is usually a sign of submission, rather than dominance, and is more common in males than in females.

Usually they are pale, but when the male becomes excited or during courtship, the caruncles, wattle and snood all engorge with blood, become bright red or blue, and enlarge. The beard (a tuft of modified brush-like feathers) also becomes erect.

A low (3-4m) branching tree, with slender, upturned branches that form a canopy. The trunk is first prostrate but becomes erect as the plant matures. Each stem is topped with a dense tuft of slender, drooping leaves. Older dead leaves are persistent around the stems just below the tuft.

The third, fourth and fifth rays of the male's anal fin are formed into a tube-like structure in which the sperm of the fish is ejected.Kapoor BG and Khanna B (2004) Ichthyology Handbook pp. 497–498, Springer Science & Business Media. . When ready for mating, the gonopodium becomes erect and points forward towards the female.

An erect human penis. The pubic hair has been removed. The length of the flaccid penis is not necessarily indicative of the length of the penis when it becomes erect, with some smaller flaccid penises growing much longer, while some larger flaccid penises growing comparatively less. Generally, the size of an erect penis is fixed throughout post-pubescent life.

The penis is the male intromittent organ. It has a long shaft and an enlarged bulbous-shaped tip called the glans penis, which supports and is protected by the foreskin. When the male becomes sexually aroused, the penis becomes erect and ready for sexual activity. Erection occurs because sinuses within the erectile tissue of the penis become filled with blood.

"Fibrinolytic system of the armadillo Chatophractus villosus (Xenarhra, Dasypodidae)" Juan Tentoni, et al. Scientists conducting studies on the C. villosus penis muscles revealed this species' very long penis exhibits variability. During its waking hours, it remains hidden beneath a skin receptacle, until it becomes erect and it projects outside in a rostral direction. During its slow wave sleep phase, penile protrusion makes some very complex movements.

During copulation it becomes erect due to engorgement with blood or lymph, though in many animals it also contains a stiff or even bony support structure. When not in use, its soft penile tissue is usually flaccid, and depending on the species, may be retracted into the body. The anatomy of the penis varies widely according to species. However, the penis evolved only once in the evolutionary history of amniotes.

Inside the pouch, the nourished young develop quickly. In the second week, the rhinarium becomes distinctive and heavily pigmented. At 15 days, the external parts of the ear are visible, although these are attached to the head and do not open out until the devil is around 10 weeks old. The ear begins blackening after around 40 days, when it is less than long, and by the time the ear becomes erect, it is between .

In addition to their appearance they possess aspects of their physiology that make them completely unique amongst parrots. Vasa chicks are known to hatch after only 18–20 days of incubation, which is highly irregular as parrots of the vasa size range tend to take up to 30 days to hatch. The male vasas' cloaca is able to invert into a hemipenis, which becomes erect during mating – a feature unique to the genus. This phallus is associated with prolonged matings enforced by a copulatory tie.

These piercings pass horizontally through the shaft. Since the piercing passes directly through the corpora cavernosa, it is likely that this piercing will bleed. Puncturing an artery cause significant bleeding; the piercing will likely have to be reset. This piercing is sometimes recommended to be done with an erect penis to avoid the chance of the piercing pinching when the penis becomes erect; unfortunately this practice leads to even more bleeding as both erectile chambers of the penis are engorged with blood while it is erect.

Unlike human sexual intercourse, where the male penis commonly becomes erect before entering the female, canine copulation involves the male first penetrating the female, after which swelling of the penis to erection occurs, which usually happens rapidly. Knotting Male canines are the only animals that have a locking bulbus glandis or "bulb", a spherical area of erectile tissue at the base of the penis. During copulation, and only after the male's penis is fully inside the female's vagina, the bulbus glandis becomes engorged with blood. In coyotes, when the female's vagina subsequently contracts, the penis becomes locked inside the female.

During the approach the pole vaulter sprints down the runway in such a way as to achieve maximum speed and correct position to initiate takeoff at the end of the approach. Top class vaulters use approaches with 18 to 22 strides, often referred to as a "step" in which every other foot is counted as one step. The run-up to the vaulting pit begins forcefully with the vaulter running powerfully in a relaxed, upright position with knees lifted and torso leaning very slightly forward. The head, shoulders and hips are aligned, the vaulter increasing speed as the body becomes erect.

An erect horse penis At the time of penetration, the canine penis is not erect, and only able to penetrate the female because it includes a narrow bone called the baculum, a feature of most placental mammals. After the male achieves penetration, he will often hold the female tighter and thrust faster, and it is during this time that the male's penis expands. Unlike human sexual intercourse, where the male penis commonly becomes erect before entering the female, canine copulation involves the male first penetrating the female, after which swelling of the penis to erection occurs. An elephant's penis is S-shaped when fully erect and has a Y-shaped orifice.

At the time of penetration, the canine penis is not erect, and can only penetrate the female because it includes a narrow bone called the "baculum", a feature of most placental mammals. When the male achieves penetration, he will usually hold the female tighter and thrust deeply. It is during this time that the male's penis expands and it is important that the bulbous gland is far enough inside for the female to be able to trap it. Unlike human sexual intercourse, where the male penis commonly becomes erect before entering the female, canine copulation involves the male first penetrating the female, after which swelling of the penis to erection occurs, which usually happens rapidly.

In one type of inverted nipple, the nipple easily becomes erect when stimulated, but in a second type, termed a "true inverted nipple," the nipple shrinks back into the breast when the areola is squeezed. According to La Leche League, "There is debate about whether pregnant women should be screened for flat or inverted nipples and whether treatments to draw out the nipple should be routinely recommended. Some experts believe that a baby who is latched on well can draw an inverted nipple far enough back into his mouth to nurse effectively." La Leche League offers several techniques to use during pregnancy or even in the early days following birth that may help to bring a flat or inverted nipple out.
