An innovative and modern sex poses definer. The definer is between a teaching game and a visual pleasure. Each postcard on one side shows the pose - using a relatively abstract and genderless illustration. And on the other side there is an explanation and detail about it and visual parameters regarding the same position determined according to a preliminary internet questionnaire I did. The main concept and goal of the definer for me is to normalizing a healthy discourse in society on issues like sex and gender. The definer presents an alternative to learning and enjoying sexual intercourse without being sexual, intimidating, perverted, or masculine.
