Yes, in some animal species, the male is more attractive. This for the purpose of attracting the females for mating. In the animal species, the male is by nature, already attracted to the female. For example, the male Mallard duck is colorful, green head/neck, a little purple/blue on the side, and a little white. The female is mostly brown/grayish tones, but still a little purple/blue/white on the side. Same with the male peacock, it has the beautiful, colorful tail we have all seen, whereas the female does not. In humans, the woman is considered more attractive...that's why men tend to "look" at them. I think in this case, the woman attracts the men and she chooses the one that appeals to her.
