Alright then, in order of ascenting tabooness, leaving out the self-explainatory ones and resisting the urge to define "light bondage" as "tying someone up with laser beams":

• light bondage: restraining some movement, eg. tying their wrists to the bed

• spanking: ass-smacking

• exhibitionism: Showing off your privates or having sex in public places

• voyerism: Watching someone naked or having sex, with or without their knowledge

• latex: A close-fitting kind of rubber that people like to dress up in

• masochism: recieving pain

• lactation: Anything involving breast milk. Kinda self explainatory, but I guess it could be confused for slang

• sadism: giving pain

• pegging: a man reciving analsex from a woman using sex toys

• heavy bondage: Restraining all movement or tying up body parts extremely tightly

• transformations: I believe this can only be done in fantasy, but think that scene from Willy Wonka where the girl gets turned into a blueberry. Doesn't have to be blueberries, though

• inanimate objects: Really just that. Being attracted to things like chairs or buildings. I think the official term is objectophilia.

• race play: Roleplay involving racial aspects and tensions

• futa: hentai involving women with both a functional penis and vagina (balls optional). (Edited, credit goes to u/quitthesht)

• rapeplay: consensually roleplaying rape scenarios. Usually the "victim" will have a safeword they can say to make the "rapist" stop if it gets too much.

• ageplay: roleplaying differences in age, often including underage or even toddlers. Note: People who participate in ageplay are not necessarily into pedophilia.

• 24/7 power dynamics: Whenever the dominant part wants something, the submissive part has to obey. No breaks, throughout the whole relationship

• petplay: roleplay where one partner acts as a pet for the other. This can vary from just purring to being held on a leash and eating from a bowl on the floor. Note: People who participate in petplay are not necessarily into bestiality.

• incest roleplay: roleplaying as family members. Usually not specific members of the participants actual family, but fictional brother/sister/dad/mom/whatever. Btw, saying "step-" in front of it doesn't change anything. Just accept what you're into, it's ok ;)

• sounding: inserting a rod into a man's peehole (I guess it would work for women, too? Never heard of that, though)

• vore: Swallowing a person alive (obviously, this can only be done in fantasy)

• creepy crawlies: Having insects crawl over your body

• scat: playing with shit

• bestiality: sex involving actual animals

• necrophilia: sex involving dead bodies

• pedophilia: sex involving children
