How could anyone possibly answer that question ? Desire is not an artifice or an article, an instrument that would be at your free disposal. You are the body, the hormones and the drive you have. Would you have others, you would be different. It's an irresistible circle. What would i want if i was a women ? I would want what women wants in general... For now, i'm a man: i want what men wants in general. Besides, men and women individually wants many different things, of course. If that site shows anything well... that's it. But you sure can't step out of who you are, or else, well... you would be that for what you change. We're not souls, unfortunatly, who can change bodies at will to animate them of the desire we have. Desire just comes with the territory, doesn't it ? And that territory is precisely your desire with your flesh and bones and all the experiences you had, and your background and your baggages. If you're a "shemale", you simply have the desire of whom that "shemale" is (bad wording of the question-sorry to all t-ladies).
A french philosopher of the beginning of the last century, Henri Bergson, used to say that there is no "possible", only the "actual". We can contemplate possibilities all we want to reflect on life, on the world, on society yet, all what exist is in the actual, in what's realized, in what's happening. In other words, there is no "could have", "should have", "would have". There is only who we are and the efforts we endlessly make to get there in the present, whatever "there" is. Is it not the beautiful and sometimes terrible drama of human life ?

Now as strange as the question was indeed, i realize this actual post, on this site, a porn forum, where frenzied, horny people comes surfing, dick in hand, most probably fully enters the category we could call, "Weird or what ?"
