Figure caption: “Heat maps showing the distribution of the Mutual Pleasure Index for both touch and look modalities, for men and women separately. Colors represent the residuals from the correlations used to calculate the final mutual pleasure score for each individual. Positive residual scores (the red end of the spectrum) indicate that respondents had a higher preference for touching/looking at that area on the opposite-gender’s body than that gender had for receiving a touch/look on that same part of their own body. Negative residual scores (the blue end of the spectrum) indicate respondents had a lower preference for touching/looking at that area on the opposite-gender’s body than that gender had for receiving a touch/look on that same part of their own body. Residual scores close to zero (white colors) indicate close agreement between respondents’ preferences for an opposite-gender partner’s body and that gender’s preferences for their own body (thus, a high mutual pleasure score)”
