That's factually incorrect. Breasts are classified as secondary sex characteristics. What are secondary sex characteristics? [quote]Secondary sex characteristics are features that appear at sexual maturity in animals and during puberty in humans, especially the sexually dimorphic phenotypic traits that distinguish the sexes of a species, but that, unlike the sex organs, are not directly part of the reproductive system. They are believed to be the product of sexual selection for traits which display fitness, giving an individual an advantage over its rivals in courtship and aggressive interactions. They are distinguished from the primary sex characteristics — the sex organs — which are directly necessary for sexual reproduction to occur.[/quote] While not inherently needed for sexual reproduction, they act as an attractive force for the opposite sex. But hey, what am I doing? Responding to a feminist with facts? Everybody knows that's their worst fear.
