Ecchi

[citation needed] The word ecchi has been adopted by western fans of Japanese media to describe works with sexual overtones.

In western culture, it has come to be used to refer to softcore or playful sexuality, as distinct from the word hentai, which connotes perversion or fetishism.

Ecchi themes are a type of fan service, and can be found in most comedy shōnen and seinen manga and harem anime.

[11] After the Second World War, in the 1950s, interest in hentai was renewed, and people would sometimes refer to it just by the first English letter, H (pronounced as エッチ, [eꜜttɕi]).

In 1952, the magazine Shukan Asahi reported that a woman who was groped by a stranger in a movie theater reacted with "ara etchi yo" ("hey, that's perverse").

In this context, etchi should be understood as sexually forward and is synonymous to iyarashii (嫌らしい, dirty or disgusting) or sukebe (すけべ, a person with sex on the brain).

from Emiko Sugi and Oruchuban Ebichu from Risa Itō, which are aimed at the shōjo and josei audience, but contain rather explicit content.

A typical example scene would contain a male protagonist that trips over a female character, giving the impression of sexual harassment.

Graphically speaking, different techniques are used to show sexy pictures, usually by revealing parts of the female body such as the back or breasts.

For example, in some cases, though the breasts are shown on the screen, nipples and genitals are obscured by props, clothing, or effects.

This kind of censorship was typical for Lala Satalin Deviluke in To Love Ru, Blair in Soul Eater and Asuka Langley Soryu from Neon Genesis Evangelion.

In any case nosebleeds as a comedic trope are a typical masculine reaction to female nudity or semi-nudity inasmuch as they represent one extremely exaggerated component of sexual arousal – increased blood pressure.
