Are you talking about hermaphrodites? Again I suspect this is down to human instinct as to why such people don't appeal to hetrosexuals. But, and I cannot emphasis this enough, I am not a biology expert. I can only base things from my own personal expeiences.
No, I meant that in view of men, female organs are highly appealing. While in Women's view, male organs are though I am sure somewhat appealing but not to the same degree as that of theirs to men.
Women are more subtle to men when it comes to wanting to engage in sexual intercourse but I can assure you, if a women wants sex, you know. Women are slaves to instinct just as men are. They just have less fertility times in a month so are not as promiscuous as men.
You're missing my point. Its not that who wants sex more, rather its the level of sexually inciting and invoking characteristics of each gender.
My point is, that it appears to me that women evolved many more characteristics in their appearance as well as behaviors and psychology that are made to invoke sexual desire in men and generally act as attractions for the opposite sex.
All while men, on the other hand, seem not to have evolved the same level of sexual appeal in any of those, be it physical characteristics and appearance to behavioral and psychological characteristics.
