Welcome to the special interest Thread, where your weirdness is accepted among those who are as equally sick or weird as you. Keep in mind some special interestes mix with one another but are categorized for your convenience.
Most info was acquired from wiki
Here's the most common and/or uncommon:

BreathPlay (Erotic Asphyxiation)
Erotic asphyxiation or breath control play is the intentional restriction of oxygen to the brain for loveual arousal. The loveual preference for that behavior is variously called asphyxiophilia, autoerotic asphyxia, hypoxyphilia. Colloquially, a person engaging in the activity is sometimes called a gasper. The erotic interest in asphyxiation is classified as a paraphilia.

Bondage (loveual)

Bondage is the use of restraints for the loveual pleasure of the parties involved. It may be used in its own right, as in the case of rope bondage and breast bondage, or as part of loveual activity or BDSM activity.
Latex and PVC special interestism

Latex special interestism is the special interestistic attraction to people wearing latex clothing or, in certain cases, to the garments themselves. PVC special interestism and rubber special interestism are closely related to latex special interest, with the former referring to shiny clothes made of the synthetic plastic polyvinyl chloride (PVC) and the latter referring to clothes made of rubber, which is generally thicker, less shiny, and more matte than latex. PVC is sometimes confused with the similarly shiny patent leather, which is also a special interest material. Latex or rubber special interestists sometimes refer to themselves as "rubberists". Gay rubberists tend to call themselves "rubbermen".
The terms "PVC", "vinyl" and "PU" tend to be used interchangeably by retailers for clothing made from shiny plastic-coated fabrics. These fabrics usually consist of a backing woven from polyester fibers with a surface coating of shiny plastic. The plastic layer itself is typically a blend of PVC and polyurethane (PU), with 100% PVC producing a stiff fabric with a glossy shine and 100% PU producing a stretchy fabric with a silky shine. A manufacturer's label may say, for example, 67% polyester, 33% polyurethane for a fabric that contains no PVC; or 80% polyvinyl chloride, 20% polyurethane with mention of the polyester backing omitted. To add to the confusion, the plastic layer is often textured to look like leather ("leatherlook", "pleather"), as opposed to smooth ("wetlook", "patent").
Ero Guro (Or the closet you can get to Snuff, quite possibly the most uncommon of the ones I posted)

Ero Guro Nansensu, frequently shorted to Ero guro, (エログロ ero-guro?) is a wasei-eigo term that describes a literary and artistic movement from 1920s and '30s Japan. Ero guro puts its focus on eroticism, loveual corruption and decadence. While ero guro is a specific movement, many of its components can be found throughout Japanese history and culture.
The term is often used incorrectly by western audiences to mean "gore"—depictions of horror, blood, and guts. In actuality the "grotesque" term implies malformed, unnatural or horrific. Items that are researchographic and bloody are not necessarily ero guro, and ero-guro is not necessarily researchographic or bloody.
Foot special interestism

Foot special interestism, foot partialism, foot worship, or podophilia is a pronounced loveual interest in feet. It is the most common form of loveual preference for otherwise non-loveual objects or body parts
Vorarephilia

Vorarephilia (often shortened to vore) is a loveual special interest and paraphilia where arousal occurs from the idea of being eaten, eating another, observing this process, or by the general process of eating. The fantasy most frequently involves the victim being swallowed alive, and may or may not include digestion. Since the special interest is difficult, illegal, or in many cases physically impossible to achieve in real life, it is more commonly enjoyed through pictures, stories, videos, and video games. It may be seen as a variation on macrophilia in some cases, and may also be combined with other special interestes.
Necrophilia

Necrophilia, also called thanatophilia or necrolagnia, is the loveual attraction to corpses. It is classified as a paraphilia by the Diagnostic and Statistical Manual of the American Psychiatric Association. The word is artificially derived from the ancient Greek words: νεκρός (nekros; "dead") and φιλία (philia; "love"). The term appears to have originated from Krafft-Ebing's 1886 work Psychopathia loveualis.
Rosman and Resnick (1989) reviewed information from 34 cases of necrophilia describing the individuals' motivations for their behaviors: these individuals reported the desire to possess an unresisting and unrejecting partner (68%), reunions with a romantic partner (21%), loveual attraction to corpses (15%), comfort or overcoming feelings of isolation (15%), or seeking self-esteem by expressing power over a homicide victim (12%), or not interested in conversation(5%).
Furry fandom

Furry fandom is a fandom for fictional anthropomorphic animal characters with human personalities and characteristics. Examples of anthropomorphic attributes include exhibiting human intelligence and facial expressions, the ability to speak, walk on two legs, and wear clothes. Furry fandom is also used to refer to the community of people who gather on the Internet and at conventions.
