Hmph. It sounds like a fetish to me.
While reading the articles you posted, I couldn't help but draw parralells to people who also seek out things like BDSM, latex, feet, or any other uncommon sexual practice. I would argue that no second sexual revolution is coming, at least not in the context of the sexRev of the late 60's and early 70's. If anything, this may hinder the acceptance of Transgender people into mainstream society, since they may now be looked at as subsidising "unwholesome" or "dirty" sex for men by the more conservative elements of our society, a viewpoint I personally find appalling and unacceptable.
Coming from the standpoint of a mostly straight male, I find nothing particularly exciting about sexual contact with a transgender woman. I suppose that should the occasion arise, (I would like to think) I would see the person as female. I would certainly be interested in that person's experience in transitioning.
It should not be overlooked that men seeking porno are generally looking for entertainment, to satisfy sexual fantasy. Similarly, IMO, men seeking transgender porn may be trying to satisfy their own desire for femininity. Either that, or attemping to identify their homosexual urges with a preson who is visually female, assuming they have issues with said homosexual urges. My opinion.
