Whenever a boot was placed near the first, a common chimpanzee born in captivity, he would invariably stare at it, touch it, become erect, rub his penis against the boot, masturbate, and then consume his ejaculate. The second, a guinea baboon, would become erect while rubbing and smelling the boot, but not masturbate or touch it with his penis.

Within a few hours of birth, the calf can run around and is almost indistinguishable from a one- week-old. However, for the first 1–3 weeks, it spends most of its time hiding; its coat pattern providing camouflage. The ossicones, which have lain flat while it was in the womb, become erect within a few days. Mother South African giraffe with calf.

The post nasal ridge of this species is more developed, in frontal view a T-shaped indentation is often apparent. The width between the outer canines is less than 5.6 mm. The ears fold down when the bat is roosting, and these become erect as it begins to take flight. The swollen form of the muzzle and presence of skin flaps is typical of the genus.

Like the rest of the tragopans, males have two pale blue horns that become erect during mating. Its lappet, a decorated flap, hangs from the throat and is brightly colored. This lappet can be expanded and exposed during mating season as well. Females are not as brightly colored as the male tragopan, for they do not need the extravagant appearance to attract a male counterpart.

In lizards and snakes, males possess paired hemipenes, each of which is usually grooved to allow sperm transport and spiny or rough at the tip to allow firm attachment to the female. To become erect, a hemipenis is evaginated (turned inside out) through muscle action and engorgement with blood. Only one is inserted into the female's cloaca at a time. In reptiles, the phallus has an open sulcus instead of a closed urethral tube.

Holmes underwent a clitorectomy, described as a "clitoral recession", at age 7, at The Hospital for Sick Children in Toronto. This surgery was undertaken because her clitoris "could become erect", and the surgery has affected her life ever since, including repeated pelvic exams, adolescent sexual experiences, fear of intimacy, and feelings of difference and embarrassment. Holmes describes how clinician "promises of sexual normalcy are not being met" by surgical intervention. Holmes refers to herself as "still intersexual" after medical intervention.

The karyotype of the Muscovy duck is 2n=80, consisting of three pairs of macrochromosomes, 36 pairs of microchromosomes, and a pair of sex chromosomes. The two largest macrochromosome pairs are submetacentric, while all other chromosomes are acrocentric or probably telocentric for the smallest microchromosomes. The submetacentric chromosomes and the Z (female) chromosome show rather little constitutive heterochromatin (C bands), while the W chromosomes are at least two-thirds heterochromatin. Male Muscovy ducks have helical penises that become erect to in s.

The effect is that of a hairy bear paw, whence both common and scientific name (arktos bear + mecon poppy). The solitary terminal flowers are typical of poppies, with 2-3 sepals and 4-6 petals, either white or yellow, and starting out as nodding bud before become erect. The fruit capsule has 4-6 valves, opens from the top as it dries, releasing a handful of small wrinkled black seeds. Arctomecon habitat is typically the harshest and driest soils of the Mojave, where few other plants survive.

The flowers are pendulous when young, but become erect when they begin to mature into the fruit which is a capsule. The flowers are 9–12 mm long and produced in a cluster of 1–11 together at the apex of the inflorescence, which is a raceme. It flowers between early summer and mid autumn; plants that flower in summer are yellow and sparsely hairy, while those that flower in autumn are red and densely hairy. These two color "forms" overlap in flowering time.

While the bulbs are considered the equivalent of the male spongiosum, they do not completely encircle the urethra. The thin corpus spongiosum of the penis runs along the underside of the penile shaft, enveloping the urethra, and expands at the end to form the glans. It partially contributes to erection, which are primarily caused by the two corpora cavernosa that comprise the bulk of the shaft; like the female cavernosa, the male cavernosa soak up blood and become erect when sexually excited. The male corpora cavernosa taper off internally on reaching the spongiosum head.

The frill-necked monarch measures around 14 cm (5.5 in) in length, and the neck feathers can become erect into a small frill; the male is predominantly black and white, and can be distinguished from the similar and more common pied monarch by its all-white breast-the latter species having a broad black breast band. The throat, nape, shoulders, and rump are white while the wings and head are black. It has an eye-ring of bare skin, and a bright blue wattle. The bill is pale blue-grey and the eyes are dark.

Men may also rub or massage the glans, the rim of the glans, and the frenular delta. Some men place both hands directly on their penis during masturbation, while others may use their free hand to fondle their testicles, nipples, or other parts of their body. The nipples are erogenous zones, and vigorous stimulation of them during masturbation usually causes the penis to become erect more quickly than it would otherwise. Some may keep their hand stationary while pumping into it with pelvic thrusts in order to simulate the motions of sexual intercourse.

In some species, the awns can contribute significantly to photosynthesis, as, for example, in barley. The awns of wild emmer wheat spikelets effectively self-cultivate by propelling themselves mechanically into soils. During a period of increased humidity during the night, the awns of the spikelet become erect and draw together, and in the process push the grain into the soil. During the daytime the humidity drops and the awns slacken back again; however, fine silica hairs on the awns act as ratchet hooks in the soil and prevent the spikelets from reversing back out again.

The outside of the munition was surrounded by a "coronet" of spring steel strips that were held flat against the sides of the mine. After landing on the surface a small explosive device would fire and release the coronet springs such that the mine would become "erect" on the surface, with their self- forging fragment warhead pointing vertically upwards. The cylindrical case of the mine was made from dimpled steel and on detonation would spread small steel anti-personnel fragments, rather like a hand-grenade, in all radial directions. They would explode at preset intervals or if disturbed.

When dry, there is a bend joint between the foot and the shaft so that it points up and the hair is more or less pressed against the cypsela. When wet, the joint stretches and the hairs become erect. The cypsela hairs are mostly of uniform thickness, around long, with a short cleft, but some such as F. anthemidodes have very short hairs, while others such as in the section Lignofelicia have languid, silky hairs of up to long. Hairs at the base of the cypsela and on the vascular bundles are often different from the rest.

Drawing of a dog with raised hackles In mammals, the hackles are the hairs of the neck and back which become erect when the animal is fearful, as part of the fight- or-flight response, or to show dominance over subordinate animals. Raising the hackles causes the animal to appear larger, and acts as a visual warning to other animals. Raised hackles are used by grey wolves as a dominance behavior, by moose preparing to attack, and by cats and striped hyena which are fearful or threatened. The process by which the hair is raised is called piloerection.

Wild emmer wheat spikelets effectively self-cultivate by propelling themselves mechanically into soils with their awns. During a period of increased humidity during the night, the awns of the spikelet become erect and draw together, and in the process push the grain into the soil. During the daytime, the humidity drops and the awns slacken back again; however, fine silica hairs on the awns act as hooks in the soil and prevent the spikelets from backing out. During the course of alternating stages of daytime drying and nighttime humidity, the awns' pumping movements, which resemble a swimming frog kick, will drill the spikelet or more into the soil.

The two main characters are thinly-veiled versions of two of Farmer's favorite characters, Tarzan and Doc Savage. Called "Lord Grandrith" and "Doc Caliban", respectively, the two are recognizable as the iconic characters, but still unique. The two, half-brothers with the same father (the infamous Victorian era serial killer Jack the Ripper) share a horrible affliction thanks to the powerful elixir that gives them near-eternal life. At the start of the novel they have discovered that they can no longer engage in sexual activity except during acts of violence (their penises become erect only during an act of violence) and they ejaculate after taking lives.

Before jumping, they glue a silk thread to the surface that they are jumping from so that if they miss the target, they can climb up the thread and try again - However, they may 'abseil' with a silk thread if they wish to descend from a height safely, for instance they have been documented 'abseiling' from ceilings. They ignore unappetising insects such as ants. There are no extensor muscles at the 'hinge joints' of the spider leg, instead joints extension is due to the haemocoelic blood pressure in the leg. The most significant evidence that this extension is due to hydraulic forces is that the leg spines become erect during the jump, a result of increased body pressure which can be demonstrated on many spiders.

Komisaruk's study was the first to map the female genitals onto the sensory portion of the brain; it indicates that sensation from the nipples travels to the same part of the brain as sensations from the vagina, clitoris and cervix, and that these reported orgasms are genital orgasms caused by nipple stimulation, and may be directly linked to the genital sensory cortex ("the genital area of the brain"). An orgasm is believed to occur in part because of the hormone oxytocin, which is produced in the body during sexual excitement and arousal and labor. It has also been shown that oxytocin is produced when a man or woman's nipples are stimulated and become erect. Komisaruk also relayed, however, that preliminary data suggests that nipple nerves may directly link up with the relevant parts of the brain without uterine mediation, acknowledging the men in his study who showed the same pattern of nipple stimulation activating genital brain regions.
