Corner masturbation... how lewd! By pressing one's genitals against the numerous "corners" that exist and rubbing them, one can achieve "corner masturbation." It is said to be a trigger for sexual awakening as well, with women who have never masturbated accidentally touching their genitals to a corner and feeling pleasure, thus beginning to masturbate. Various stimuli different from imagination will make them captives of "corner masturbation."
