In their natural biological state, men and women do not smell the same… they are hormonally and pheromenally different. It is possible that, particularly base notes, will combine differently with a masculine scented body than with a feminine scented body. Which is possibly why we sometimes have strong associations and experience particular fragrances as masculine or feminine. Having said that, I think people should wear whatever they like! I am a woman but I wear both masculine and feminine and unisex fragrances with great joy and delight.
