Male characters, are always seen more props for the hentai girls to perform their acts on. I dunno what people were thinking when they claim hentai “objectifies” the females. If anything, it is the guys who are often faceless one dimensional sex toys in hentai genre.
They also have two distinct types of voices commonly heard from them.
The scared, unsure, submissively confused first timers who sound like needs with weasly voices. They tend to be the loudest.
The creepy, sly, cunning sounding voices that are often used for rapists and perverts.
