Toxicity is, in short, a disease just a hair short from being an STD. Technically defined as an infection, the condition's full name is toxic sanguinarian biochemical interdependance, otherwise abbreviated to TSBI. Symptoms can be subtle and difficult to identify without prior knowledge of the disease and whether the individual is/was exposed to it.

Although most carriers of the infection are prompt to inform their partners of the possibilities, there are situations in which the individual can be exposed unknowingly and without being informed until a doctor diagnoses him/her. TSBI is highly contagious and is highly concentrated throughout all of the carrier's bodily fluids including blood, saliva, urine, and semen/vaginal fluids. Ingestion of any of these fluids whether by mouth, vaginally, or anally carries a high chance of infection.

Discovered in the early 1600's, TSBI can be misconstrued very easily for other diseases, and from the surface can look similar to classic tales of vampirism. Carriers of TSBI are born with the infection latent, and cannot catch it, but parents almost always inform their children of the facts at the same time as they teach them about the reproductive system. When toxic fluids are passed from carrier to another individual, that individual may possibly become 'infected' with TSBI. Infection is of course active, rather than latent as the carrier's form of infection.

Carriers of TSBI only show very few symptoms, and occasionally will show none at all. A carrier can sometimes be identified by a faint glowing quality to their eyes, mouths, markings on the fur, and reproductive organs. This is caused by the adaptation in skin cells to keep the disease from manifesting in the same way as an infection; by providing a blood-flow more swift and in larger quantities than normal. This leads to a higher heart rate and body temperature, as well as an increase in natural libido thanks to the increase in blood to the reproductive organs. Active forms of TSBI include symptoms of dependance on the carrier's specific biological imprint that usually manifest in one of two ways; a constant desire to be ingesting those fluids, or more often a sexual addiction that cannot be contained. The sexual addiction revolves around a physical need to ingest more of those fluids, normally through sexual acts such as oral sex, vaginal sex, or anal sex. Because of TSBI's unique biohazardous qualities, the individual who becomes infected craves sex only with the carrier from whom he or she contracted the disease. Only the fluids of that individual carrier can counteract the symptoms.

If the infected person does not have some form of the carrier's DNA-carrying fluid in his or her system at all times, their body reacts by slowing the production of red blood cells, causing symptoms much like leukemia and other forms of cancer. The infected person may feel tired, weak, or dizzy, and these quickly escalate into a massive malfunctioning of the body. The heart rate slows dramatically, the extremities may grow numb and begin to turn blue after several hours without exposure to the carrier's fluids. One of the largest danger signs is if the infected individual faints or blacks out; if not treated within the hour, he or she has a high probability of going into a coma. If he or she experiences a lack of the carrier's fluids on a constant basis too often, other conditions such as epilepsy can form thanks to the damage to his or her neurological state of being.

Because of the brain's ability to adapt, the infection can be made more pleasant for most infected people thanks to the mental stimulation caused by physical need for those fluids. The most common plus is a high rise in libido in both carrier and partner, leading to a more varied and enjoyable sex life. Often the carrier and partner develop a stronger bond than most sexually active couples. There has recently been a high rise in BDSM interest in the TSBI community; the positions of dominance and submission have become favorites between these couples, thanks to the similarities between their own biological relationship and their sexual one. Because the infected individual requires the carrier's fluids to live, the carrier can usually control his or her partner into a similarly submissive behavior in order to 'earn' his or her antidote. Surprisingly, there are even individuals who seek out a carrier in order to form this type of 'total power exchange' relationship.

Many carriers of TSBI sport biohazard symbols as tattoos, jewelry, or clothing. Most are proud of their status and enjoy their ability to 'own' another living being who will love them and need them in a deeper way than normal romantic relationships. Although it is a different lifestyle than most people can consider as an option, TSBI relationships tend to be strong and well-founded, and it is in no way a crippling disease. No cure has been found besides the natural way to keep symptoms at bay for short intervals, although couples who have been together for a long period of time seem to have more control over when and where doses are needed.
