Hmm, we seem to be debating at cross purposes. I thought you were originally arguing that your view was what SHOULD be the representation of the Amazons in the comics, not what the various writers have actually done. But it seems that you're discussing the actual representation. And I can't really comment, since the Perez run was the only Wonder Woman comics I ever read.
My argument was what I thought should have been the Amazon depiction. What would make the most sense if I was writing the title. From that perspective, asexuality makes more sense to me, than the notion that a heretofore predominantly heterosexual group of women would suddenly become lesbian in the absence of men. While some homosexuality can be explained by environmental circumstances, most people agree that homosexuals are generally born that way. So, I don't see many women converting, even in a fictional scenario. Having left sexuality behind sounds like a better narrative to me, especially since these women are immortal, and don't need to procreate.
I just realized too that we're talking at crossed purposes. Sorry about that.
