Perisexual

Ritual beatings were his first perisexual experiences, and they are vividly and enthusiastically remembered and described in his letters.

Since he has just clarified the Edo tendency to distinguish between perisexual and sexual acts, convincingly showing that male-male sexual acts were not problematized before the Meiji period, his position on this issue is not particularly persuasive.

A number of sociocultural and peri-sexual behaviours and practices were thought to be important in determining the epidemiology of STI among the students.
