This is my attempt in response to challenge to visualize data from National Survey of Sexual Health and Behavior.
I have applied Principal Component Analysis and have used biplot as indicator to create a map, which shows distribution of various sexual activities and showing separation of men and women by age on the map.
The 1st PC (horizontal axis) separates data by gender-specific activities: in the middle there are activities common to both genders, to the left – men-specific and to the right – women-specific activities.
The 2nd PC (vertical axis) separates by degree of “advancement” in type of activity, masturbation being the most conservative one common to very youngest and oldest men and women, and anal sex being the most rare mostly common for the most sexually active age group of both men and women.
