School of Seduction

*Ranma ½* has now entered *The Hentai Zone*.

A school where one learns to... well, be a prostitute. We don't know if people like Double Pole-Dancing after lunch, or having to do homework on bondage.

Related to Band of Brothels.

Despite the title, this trope is completely unrelated to Ohtori Academy.

Examples of School of Seduction include:

Anime & Manga

The manga School of Water Business is about one of those.

Fan Works

In the Ranma ½ parody webcomic The Hentai Zone, Fūrinkan High School becomes one of these, as pictured above.

Literature

The Bene Gesserit in Dune. Later in the series, and more explicitly, the Honored Matres.
Codex Alera: Lord Kalare is said to have used a training program incorporating this as well as other things for his female agents.
Memoirs of a Geisha shows how the girls work their way up in an apprentice-type system. While a literal example of this trope, as geisha are taught to be seductive and beautiful, they are not taught actual sex, and the instances where they work as prostitutes are unconnected with their training.
The Court of Night Blooming Flowers in Jacqueline Carey's Kushiels Legacy series is a collection of brothels in a society in which prostitution is considered a sacred calling. Courtesans who are born in or adopted into the Night Court are given instruction in the arts of the salon (music, etiquette, etc.) as well as the arts of the bedchambers. It's an apprenticeship system, with titles and rites of initiation. Slight Squick in that you are expected to pay off your debt to the House that raised and trained you by working for them (though not necessarily as a prostitute).
The Rainbow Cadenza is a science fiction novel by J. Neil Schulman, in which women are drafted not as soldiers but as prostitutes (as men vastly outnumber women). One scene has the female protagonist being taught fellatio by a homosexual instructor.

Live-Action TV

The various Companion temples in Firefly.
The Wife Bank in Lexx, at which unwanted girls are abandoned by their parents, raised in boxes by impersonal holograms to be fawning and sexually insatiable, and then given as presents to the sons of upper-class families. (Graduates who "fail to perform their wifely duties" are electronically brainwashed into "love slaves", with an unstable, psychotic, one-track-minded devotion—and an expiry date. Yep, Crapsack World.)

Holographic Matron: Lesson 376. Your husband asks you, "Do you think I'm fat?" What is the correct answer?
1. "No!"
2. "It's not what you look like on the outside, but the man on the inside that matters to me."
3. "I like a man with a lot of meat on his bones! Can we get naked now and play Ride the Tower of Power?"
Zev: (hesitantly) "It's not what you look like on the outside, but the man on the inside that matters to me"?
Holographic Matron: Wrong! The correct answer is: "I like a man with a lot of meat on his bones! Can we get naked now and play Ride the Tower of Power?"

Tabletop Games

The School of Performing and Creative Arts in GURPS Illuminati University (illustrated by Phil and Kaja Foglio).
The Vodacce courtesan schools in the 7th Sea tabletop RPG.

Video Games

Eva in Metal Gear Solid 3: Snake Eater admits to going to one of these as a child... where the Boss was an instructor. Considering her "talents" (both types), without a doubt it was one of these, or at least had it as a major. IIRC, according to the Metal Gear Solid Database, the "Charm School" was a Philosopher-run facility for the training of female spies and sleepers, so it was probably more the latter case.

Real Life

It's claimed the KGB had one of these in Real Life, to train Honey Trap agents.
Jay Leno once commented on reports that a real one had opened up in Amsterdam. "I don't know which would be worse: failing out or being Valedictorian."
High-class prostitutes—geisha, hetairai, courtesans—often had to be trained for the high-class portion of their occupations.
- Geisha are not prostitutes. They weren't even taught sexual acts, and focused on the arts, like music and dancing.
