"For your information" can impress others as condescending. However, Keith Russell began in a confrontational manner, which could trigger a condescending tone, don't you think? More is happening here than intellectual discussion of a subject, and awareness is a good thing.
This wikipedia article comes with a picture of the statue of Adonis, and who can forget the statue of David, or the muscular thinking man?
Several things play into sexual attractiveness. The importance of symmetry has been researched, and is artistically important.

Symmetry
Symmetrical faces and bodies may be signs of good inheritance to women of child-bearing age seeking to create healthy offspring. Some studies suggested that women at peak fertility were more likely to fantasize about men with greater symmetry.[13] Studies suggest women are more attracted to men with symmetrical features, and noticed correlations between symmetry and other variables typically associated with masculinity, such as greater height, broader shoulders, and smaller hip-to-waist ratios.[14] Facial and body symmetry may indicate good health, which is a desirable feature.[14] The symmetrical nature of a male partner may be a variable influencing whether a woman, during sexual intercourse, is able to achieve an orgasm; one study suggested that orgasmic frequency increases from 30% to 75% when their male partners were described as more symmetrical.[15]
