Khloe and Lamar did it. Calvin Klein did it. Dolce and Gabbana did it. What's the problem with having a fragrance that both you and your man can wear? Well let me tell you.
It's counterproductive. Perfumes are worn to further build your appeal to those around you--like flowers and bees-- to increase your attractiveness.

Hence, there is usually a noticeable difference between men's colognes and women's perfumes. What's the point of wearing the same perfume as the hottie next to you?
