Does being a zero mean that I don't see the attractiveness of other men? I have never been physically attracted to a man. But, I am often talking to my wife and others about the attractiveness of particular men.
I have had man crushes. There are people that I would like to know better and get close to.
I call that being homosocial. I think a lot of men enjoy the company of other men to that of women. Same applies to women, too. I think people can sometimes be more honest and open with members of their same gender.
We cannot choose our desires, and I sometimes think that they choose us. If you are not attracted to men physically, there is nothing you can do to change that, and of course, there is nothing wrong with it either. Desire simply IS! It is what it is without reason, or logic, or intention, or meaning. And if desire is not present, you cannot invent it, force it, or coerce it.
Most people can recoginze the attractiveness, or lack thereof, in members of their own gender without experiencing desire or attraction themselves.
