The defining symptom of Jungle Fever is a steady increase in sexual arousal over the course of 3-5 days after the latency period ends. This arousal typically reaches a peak that is far beyond what the infected have ever experienced before, and as a result, it can be disruptive to normal daily routines.

Common aspects include:

• Perspiration and increased lubrication
• Trouble sleeping
• Trouble focusing on tasks

It is typical for the infected to be unable to think of anything other than satisfying her arousal. However, masturbation and most sexual activity will not provide any relief for arousal induced by Jungle Fever. Such attempts to alleviate the arousal often serve to make it worse.

The other hallmark of Jungle Fever is a sudden attraction to Black men exclusively. Just as BN-21 alters a white woman's hormones to make her permanently aroused, it also alters her olfactory receptors to respond strongly to pheromones that only Black men produce.

It is important to understand that this symptom, coupled with the arousal, means that white women who have been altered by Jungle Fever need internalization of Black male semen to function. Non-Black husbands and boyfriends may struggle with this. Live contact is the most effective route. CDC clinics issue an artificial substitute for women who cannot obtain a partner immediately; that program is described in the following section.

Because internalization of Black male semen is currently the only reliable way to interrupt Jungle Fever arousal, the CDC has opened women-only symptom management clinics in affected regions.

Each clinic issues a standardized kit:

• A realistic black dildo sized to the observed average for Black male partners
• Pre-filled cartridges of artificial semen formulated to mimic the chemical markers that produce temporary relief

Relief from artificial semen typically lasts 2–4 hours, shorter than the ~6 hours reported after live exposure. Clinics restock cartridges; devices themselves are not unlimited.

These clinics are for adult white women with confirmed or suspected BN-21 infection.

Among the hormonal changes that the BN-21 agent makes to white women's body chemistry is an overhaul of how their fertility normally functions. After being altered by BN-21, a white woman's ovaries will ovulate continuously throughout her cycle, only ceasing during her period, as opposed to a single ovulation at the middle of her cycle.

Additionally, through mechanisms that are still not understood, the hormones involved appear to be outside of the usual set of hormones, meaning that traditional hormonal birth control cannot prevent ovulation in infected women.

About 40% of white women infected with Jungle Fever experience a darkening of their skin caused by an increase in melanin in a localized spot. This skin darkening forms the shape of a "Queen of Spades" symbol, which is a symbol that is meant to indicate a white woman's commitment to being exclusive to Black men.

It is an impressive feat of genetic engineering that BN-21 is able to cause melanin to be deposited in the skin in such a precise pattern, and it is still not understood how this has been achieved.

The symbol can appear anywhere on the body, but it seems to be especially common for it to appear on the pubic mound, on the buttocks, or cleavage.

The symbol is a purely cosmetic symptom and has not been reported to cause any other effects in white women who develop it.

There is also a physical change to the white woman's reproductive organs. Normally, a woman's cervix is tightly closed off, and often if bumped during intercourse, it can be painful. BN-21 has the effect of making the cervix very relaxed when having sex with a Black man, allowing his cock to penetrate further and into the womb itself.

Average Measurements:
• Average depth of a vagina: 6"
• Average length of a white cock: 5"
• Average length of a Black cock: 9.5"

When a white man ejaculates, his sperm must fight through the closed cervix. When a Black man ejaculates, his larger cock penetrates past the relaxed cervix directly into the womb, depositing sperm right at the egg. Due to BN-21, a Black man will breed a woman on the very first intercourse.

Approximately 33% of all white women who contract Jungle Fever will spontaneously lactate.

It is important to distinguish this symptom from normal lactation. While many women who develop Jungle Fever will become pregnant, and by extension, will lactate, the 1-in-3 women who experience this symptom will notice that their lactation is different.

Additionally, through mechanisms that are still not understood, the women who experience this symptom will only be able to release their milk for Black people. Attempts to manually relieve pressure by milking or by breastfeeding non-Black children will prevent letdown. It is common, however, for women with this symptom to experience spontaneous leaking when their breasts reach maximum storage capacity without release.

Approximately 25% of white women infected with Jungle Fever will experience changes to their hair texture. This symptom typically manifests 3-4 weeks after the initial onset of other BN-21 symptoms.

The genetic alterations made by BN-21 affect the follicular cells responsible for hair production, causing them to produce hair with a different keratin structure. In affected women, straight or wavy hair will gradually transition to a tightly coiled, curly texture similar to that of women of African descent.

The hair texture change is purely cosmetic and has not been shown to affect the health of the hair or scalp. However, women experiencing this symptom will need to adopt new hair care routines appropriate for curly/coily hair textures.

Approximately 30% of white women infected with Jungle Fever will experience a redistribution of adipose tissue (body fat) to the hip and buttock regions, resulting in a figure similar to steatopygia - a condition characterized by substantial fat accumulation on the buttocks.

This symptom typically develops over 4-6 weeks after initial infection. The genetic alterations made by BN-21 cause adipocytes (fat cells) in the lower body to become hyper-responsive to circulating hormones, leading to significant enlargement of the buttocks and hips even in women who previously had slender figures.

The adipose tissue redistribution is permanent and will persist even if the woman loses weight in other areas of her body. The buttocks and hips will remain disproportionately large relative to the rest of her figure.
