In some cultures, historically, unshaven legs are perceived as unattractive, while for men, fashion requirements are diametrically opposed. A man with hairy legs is perceived as a sexy male, capable of leaving a good offspring.
Thus, a woman with hair on the limbs is perceived at best as untidy, and more often as an unhealthy, with an elevated level of male hormones, not capable of producing healthy offspring. With men, on the contrary – the stronger his body is wrapped, so, therefore, he has more testosterone, and therefore, his potency and reproductive capabilities are at the maximum height.
Of course, everything described above – stereotypes and vestiges of the past. Now no one draws conclusions only on the basis of appearance – you can go and pass any analysis, there would be feelings between people. Also, all of the above is true for European and some Asian peoples. Many women of the northern continent consider the presence of hair on legs и hands a sign of freedom from prejudice and victorious feminism. So the choice is always for every concrete woman and every concrete man.
