(NSFW) – Japanese sex vocabulary

外国語を勉強する時に、先生や教科書は生きていく中で、自然に使用する重要な言葉は教えられていません。以下はセックスに関する内容です。Image from Japanese sex-ed material

When learning a foreign language your teachers and textbooks leave a huge gaping hole in your knowledge about words relating to an important, natural part of everyone’s life – sex.

I could speak Japanese functionally when I arrived in Japan and after a couple of months I was spending time with a Japanese girl who didn’t speak English.  We started to become intimate and realized that I didn’t know any vocabulary related to such things, especially the casual slang that couples would use in the bedroom.  She was amused by this and wanted to teach me.  I’ll leave the rest up to your imagination but I will say they were lessons that are hard to forget!

So I wanted to share some important but hard to come by vocabulary with you.  This isn’t comprehensive and might even vary by region a bit.

Caution real-world but not safe for work (NSFW) material ahead!  エッチに関する英単は先です。

Japanese sex educationI’ll divide the vocabulary into objects and actions and mark the words with one of four categories1:

proper(適切) – can be used in casual or formal discussion and generally said in public

light slang – casual language in relaxed contexts

slang(スラング) – casual language commonly used between friends and lovers but somewhat inappropriate to say in public

vulgar(不適切) – Crude language, inappropriate in public or around children

1 This is in general based on my study of Japanese and experience in Japan.  Context, region, and other factors may cause others to classify some of these words differently.
