BishōnenW
Bishōnen

Bishōnen is a Japanese term literally meaning "beautiful youth (boy)" and describes an aesthetic that can be found in disparate areas in East Asia: a young man of androgynous beauty. This word originated from the Tang dynasty poem Eight Immortals of the Wine Cup by Du Fu. It has always shown the strongest manifestation in Japanese pop culture, gaining in popularity due to the androgynous glam rock bands of the 1970s, but it has roots in ancient Japanese literature, the homosocial and homoerotic ideals of the medieval Chinese imperial court and intellectuals, and Indian aesthetic concepts carried over from Hinduism, imported with Buddhism to China. Today, bishōnen are very popular among girls and women in Japan. Reasons for this social phenomenon may include the unique male and female social relationships found within the genre. Some have theorized that bishōnen provide a non-traditional outlet for gender relations. Moreover, it breaks down stereotypes surrounding feminine male characters. These are often depicted with very strong martial arts abilities, sports talent, high intelligence, dandy fashion, or comedic flair, traits that are usually assigned to the hero/protagonist.

In a sexual context, groping is touching another person in a sexual manner without their consent. The term generally has a negative connotation in many societies, and the activity may be considered sexual assault or otherwise unacceptable. Touching a consenting person's body during sexual activity, massage, or medical examination is not usually considered groping, though the term is sometimes used to include clumsy, selfish, or inappropriate sexual touching. Areas of the body most frequently groped include the buttocks, breasts, vulva and thighs on a woman, and the penis, testicles and buttocks on a man. Gropers might use their hands, but pressing any part of their body against another person can be considered groping.

Japanese bondageW
Japanese bondage

Kinbaku (緊縛) means "tight binding," while Kinbaku-bi (緊縛美) literally means "the beauty of tight binding."

In Japanese, this natural-fibre rope is known as asanawa ; the Japanese vocabulary does not make a distinction between hemp and jute. The allusion is to the use of hemp rope for restraining prisoners, as a symbol of power, in the same way that stocks or manacles are used in a Western BDSM context. The word shibari came into common use in the West at some point in the 1990s to describe the bondage art Kinbaku. Shibari is a Japanese word that broadly means "binding" or "tying" in most contexts, but is used in BDSM to refer to this style of decorative bondage.
